## DESCRIPTION
       yadm  is a tool for managing a collection of files across multiple com‐
       puters, using a shared Git repository.  In addition,  yadm  provides  a
       feature  to  select alternate versions of files for particular systems.
       Lastly, yadm supplies the ability to manage a subset of  secure  files,
       which are encrypted before they are included in the repository.


## COMMANDS
       git-command or git-alias
              Any  command not internally handled by yadm is passed through to
              git(1).  Git commands or aliases are invoked with the yadm  man‐
              aged repository.  The working directory for Git commands will be
              the configured work-tree (usually $HOME).

              Dotfiles are managed by using standard git commands;  add,  com‐
              mit, push, pull, etc.

              The  config command is not passed directly through.  Instead use
              the gitconfig command (see below).

       alt    Create symbolic links and  process  templates  for  any  managed
              files  matching the naming rules described in the ALTERNATES and
              TEMPLATES sections. It is usually unnecessary to run  this  com‐
              mand,  as  yadm  automatically  processes alternates by default.
              This automatic behavior can be disabled by setting the  configu‐
              ration yadm.auto-alt to "false".

       bootstrap
              Execute $HOME/.config/yadm/bootstrap if it exists.

       clone url
              Clone a remote repository for tracking dotfiles.  After the con‐
              tents of the remote repository have been fetched, a "check  out"
              of  the remote HEAD branch is attempted.  If there are conflict‐
              ing files already present in the work-tree,  the  local  version
              will  be  left  unmodified and you'll have to review and resolve
              the difference.

              The repository is  stored  in  $HOME/.local/share/yadm/repo.git.
              By default, $HOME will be used as the work-tree, but this can be
              overridden with the -w option.  yadm can be forced to  overwrite
              an  existing repository by providing the -f option.  If you want
              to use a branch other than the remote HEAD branch you can  spec‐
              ify  it  using the -b option.  By default yadm will ask the user
              if the bootstrap program should be run (if it exists).  The  op‐
              tions  --bootstrap or --no-bootstrap will either force the boot‐
              strap to be run, or prevent it from being run, without prompting
              the user.

       config This  command  manages  configurations  for  yadm.  This command
              works exactly the way git-config(1) does.  See the CONFIGURATION
              section for more details.

       decrypt
              Decrypt  all  files  stored  in $HOME/.local/share/yadm/archive.
              Files decrypted will be relative  to  the  configured  work-tree
              (usually $HOME).  Using the -l option will list the files stored
              without extracting them.

       encrypt
              Encrypt all files matching the  patterns  found  in  $HOME/.con‐
              fig/yadm/encrypt.  See the ENCRYPTION section for more details.

       enter  Run  a  sub-shell with all Git variables set. Exit the sub-shell
              the same way you leave  your  normal  shell  (usually  with  the
              "exit"  command).  This sub-shell can be used to easily interact
              with your yadm repository using "git" commands.  This  could  be
              useful  if you are using a tool which uses Git directly, such as
              tig, vim-fugitive, git-cola, etc.

              Optionally, you can provide a command after "enter", and instead
              of invoking your shell, that command will be run with all of the
              Git variables exposed to the command's environment.

              Emacs Tramp and Magit can manage files by using this  configura‐
              tion:

                  (add-to-list 'tramp-methods
                       '("yadm"
                         (tramp-login-program "yadm")
                         (tramp-login-args (("enter")))
                         (tramp-login-env (("SHELL") ("/bin/sh")))
                         (tramp-remote-shell "/bin/sh")
                         (tramp-remote-shell-args ("-c"))))

              With this config, use (magit-status "/yadm::").

       git-crypt options
              If  git-crypt  is installed, this command allows you to pass op‐
              tions directly to git-crypt, with the environment configured  to
              use the yadm repository.

              git-crypt enables transparent encryption and decryption of files
              in a git repository.  You can read  https://github.com/AGWA/git-
              crypt for details.

       gitconfig
              Pass  options to the git config command. Since yadm already uses
              the config command to manage its own configurations,  this  com‐
              mand is provided as a way to change configurations of the repos‐
              itory managed by yadm.  One useful case might  be  to  configure
              the  repository so untracked files are shown in status commands.
              yadm initially configures its repository so that untracked files
              are  not  shown.   If  you wish use the default Git behavior (to
              show untracked files and directories), you can remove this  con‐
              figuration.

                     yadm gitconfig --unset status.showUntrackedFiles

       help   Print a summary of yadm commands.

       init   Initialize  a  new, empty repository for tracking dotfiles.  The
              repository is stored  in  $HOME/.local/share/yadm/repo.git.   By
              default,  $HOME  will  be used as the work-tree, but this can be
              overridden with the -w option.  yadm can be forced to  overwrite
              an existing repository by providing the -f option.

       list   Print a list of files managed by yadm.  The -a option will cause
              all managed files to be listed.  Otherwise, the list  will  only
              include files from the current directory or below.

       introspect category
              Report  internal  yadm  data. Supported categories are commands,
              configs, repo, and switches.  The purpose of introspection is to
              support command line completion.

       perms  Update  permissions as described in the PERMISSIONS section.  It
              is usually unnecessary to run this command,  as  yadm  automati‐
              cally  processes permissions by default. This automatic behavior
              can be disabled by setting the configuration yadm.auto-perms  to
              "false".

       transcrypt options
              If  transcrypt is installed, this command allows you to pass op‐
              tions directly to transcrypt, with the environment configured to
              use the yadm repository.

              transcrypt  enables  transparent  encryption  and  decryption of
              files    in    a    git    repository.      You     can     read
              https://github.com/elasticdog/transcrypt for details.

       upgrade
              Version  3  of yadm uses a different directory for storing data.
              When you start to use version 3 for the first time, you may  see
              warnings about moving your data to this new directory.  The eas‐
              iest way to accomplish this is by running "yadm upgrade".   This
              command  will  start  by  moving your yadm repo to the new path.
              Next it will move any archive data.  If the archive  is  tracked
              within your yadm repo, this command will "stage" the renaming of
              that file in the repo's index.

              Upgrading will attempt to de-initialize and  re-initialize  your
              submodules. If your submodules cannot be de-initialized, the up‐
              grade will fail. The most common reason submodules will fail  to
              de-initialize  is  because they have local modifications. If you
              are willing to lose the local modifications to those submodules,
              you  can  use  the -f option with the "upgrade" command to force
              the de-initialization.

              After running "yadm upgrade", you should run  "yadm  status"  to
              review  changes  which have been staged, and commit them to your
              repository.

              You can read https://yadm.io/docs/upgrade_from_2 for more infor‐
              mation.

       version
              Print the version of yadm.


## OPTIONS
       yadm  supports a set of universal options that alter the paths it uses.
       The default paths are documented in the FILES section. Any path  speci‐
       fied  by  these  options must be fully qualified. If you always want to
       override one or more of these paths, it may  be  useful  to  create  an
       alias  for the yadm command.  For example, the following alias could be
       used to override the repository directory.

              alias yadm='yadm --yadm-repo /alternate/path/to/repo'

       The following is the full  list  of  universal  options.   Each  option
       should be followed by a path.

       -Y,--yadm-dir
              Override  the  yadm  directory.   yadm stores its configurations
              relative to this directory.

       --yadm-data
              Override the yadm data directory.  yadm stores its data relative
              to this directory.

       --yadm-repo
              Override the location of the yadm repository.

       --yadm-config
              Override the location of the yadm configuration file.

       --yadm-encrypt
              Override the location of the yadm encryption configuration.

       --yadm-archive
              Override the location of the yadm encrypted files archive.

       --yadm-bootstrap
              Override the location of the yadm bootstrap program.


## CONFIGURATION
       yadm  uses  a configuration file named $HOME/.config/yadm/config.  This
       file uses the same format as git-config(1).  Also, you can control  the
       contents  of  the configuration file via the yadm config command (which
       works exactly like git-config).  For example, to disable alternates you
       can run the command:

              yadm config yadm.auto-alt false

       The following is the full list of supported configurations:

       yadm.alt-copy
              If set to "true", alternate files will be copies instead of sym‐
              bolic links.  This might be desirable, because some systems  may
              not properly support symlinks.

       yadm.auto-alt
              Disable  the  automatic  linking described in the section ALTER‐
              NATES. If disabled, you may still run  "yadm  alt"  manually  to
              create the alternate links. This feature is enabled by default.

       yadm.auto-exclude
              Disable   the   automatic   exclusion  of  patterns  defined  in
              $HOME/.config/yadm/encrypt.  This feature is enabled by default.

       yadm.auto-perms
              Disable the automatic permission changes described in  the  sec‐
              tion  PERMISSIONS.   If  disabled,  you may still run yadm perms
              manually to update permissions.  This feature is enabled by  de‐
              fault.

       yadm.auto-private-dirs
              Disable  the automatic creating of private directories described
              in the section PERMISSIONS.

       yadm.cipher
              Configure which encryption system is used by the encrypt/decrypt
              commands.  Valid options are "gpg" and "openssl". The default is
              "gpg".  Detailed information can be found in the section ENCRYP‐
              TION.

       yadm.git-program
              Specify  an  alternate  program to use instead of "git".  By de‐
              fault, the first "git" found in $PATH is used.

       yadm.gpg-perms
              Disable the permission changes to $HOME/.gnupg/*.  This  feature
              is enabled by default.

       yadm.gpg-program
              Specify  an  alternate  program to use instead of "gpg".  By de‐
              fault, the first "gpg" found in $PATH is used.

       yadm.gpg-recipient
              Asymmetrically encrypt files with a gpg public/private key pair.
              Provide  a "key ID" to specify which public key to encrypt with.
              The key must exist in your public keyrings.  Multiple recipients
              can  be  specified  (separated  by space).  If left blank or not
              provided, symmetric encryption  is  used  instead.   If  set  to
              "ASK",  gpg  will interactively ask for recipients.  See the EN‐
              CRYPTION section for more details.  This feature is disabled  by
              default.

       yadm.openssl-ciphername
              Specify  which  cipher should be used by openssl.  "aes-256-cbc"
              is used by default.

       yadm.openssl-old
              Newer versions of openssl  support  the  pbkdf2  key  derivation
              function.  This is used by default. If this configuration is set
              to "true", openssl operations will use options  compatible  with
              older  versions  of openssl. If you change this option, you will
              need to recreate your encrypted archive.

       yadm.openssl-program
              Specify an alternate program to use instead  of  "openssl".   By
              default, the first "openssl" found in $PATH is used.

       yadm.ssh-perms
              Disable the permission changes to $HOME/.ssh/*.  This feature is
              enabled by default.

       The following  five  "local"  configurations  are  not  stored  in  the
       $HOME/.config/yadm/config, they are stored in the local repository.


       local.class
              Specify  a  class for the purpose of symlinking alternate files.
              By default, no class will be matched.  The local host can be as‐
              signed multiple classes using command:

              yadm config --add local.class <additional-class>

       local.arch
              Override  the  architecture for the purpose of symlinking alter‐
              nate files.

       local.hostname
              Override the hostname for the purpose  of  symlinking  alternate
              files.

       local.os
              Override the OS for the purpose of symlinking alternate files.

       local.user
              Override the user for the purpose of symlinking alternate files.


## ALTERNATES
       When managing a set of files across different systems, it can be useful
       to have an automated way of choosing an alternate version of a file for
       a different operating system, host, user, etc.

       yadm  will automatically create a symbolic link to the appropriate ver‐
       sion of a file, when a valid suffix is appended to  the  filename.  The
       suffix  contains  the  conditions  that must be met for that file to be
       used.

       The suffix begins with "##", followed by any number of conditions sepa‐
       rated by commas.

         ##<condition>[,<condition>,...]

       Each  condition is an attribute/value pair, separated by a period. Some
       conditions do not require a "value", and in that case, the  period  and
       value  can  be  omitted. Most attributes can be abbreviated as a single
       letter.

         <attribute>[.<value>]

       These are the supported attributes, in the order of the weighted prece‐
       dence:


       template, t
              Valid  when  the  value  matches a supported template processor.
              See the TEMPLATES section for more details.

       user, u
              Valid if the value matches the current user.   Current  user  is
              calculated by running id -u -n.

       hostname, h
              Valid if the value matches the short hostname.  Hostname is cal‐
              culated by running uname -n, and trimming off any domain.

       class, c
              Valid if the value matches the local.class configuration.  Class
              must be manually set using yadm config local.class <class>.  See
              the CONFIGURATION section for more  details  about  setting  lo‐
              cal.class.

       distro, d
              Valid  if the value matches the distro.  Distro is calculated by
              running lsb_release -si or by inspecting the ID from /etc/os-re‐
              lease.

       distro_family, f
              Valid  if the value matches the distro family.  Distro family is
              calculated by inspecting the ID_LIKE line from /etc/os-release.

       os, o  Valid if the value matches the OS.  OS is calculated by  running
              uname -s.

       arch, a
              Valid  if  the  value matches the architecture.  Architecture is
              calculated by running uname -m.

       default
              Valid when no other alternate is valid.

       extension, e
              A special "condition" that doesn't affect the selection process.
              Its purpose is instead to allow the alternate file to end with a
              certain extension to e.g. make  editors  highlight  the  content
              properly.

       NOTE:  The  OS  for "Windows Subsystem for Linux" is reported as "WSL",
       even though uname identifies as "Linux".

       You may use any number of conditions, in any order.  An alternate  will
       only  be  used  if  ALL conditions are valid.  For all files managed by
       yadm's repository or  listed  in  $HOME/.config/yadm/encrypt,  if  they
       match  this  naming  convention, symbolic links will be created for the
       most appropriate version.

       The "most appropriate" version is determined by calculating a score for
       each  version  of  a  file. A template is always scored higher than any
       symlink condition. The number of conditions is the next largest  factor
       in scoring.  Files with more conditions will always be favored. Any in‐
       valid condition will disqualify that file completely.

       If you don't care to have all versions of alternates stored in the same
       directory  as  the  generated  symlink,  you  can  place  them  in  the
       $HOME/.config/yadm/alt directory. The generated  symlink  or  processed
       template will be created using the same relative path.

       Alternate  linking may best be demonstrated by example. Assume the fol‐
       lowing files are managed by yadm's repository:

         - $HOME/path/example.txt##default
         - $HOME/path/example.txt##class.Work
         - $HOME/path/example.txt##os.Darwin
         - $HOME/path/example.txt##os.Darwin,hostname.host1
         - $HOME/path/example.txt##os.Darwin,hostname.host2
         - $HOME/path/example.txt##os.Linux
         - $HOME/path/example.txt##os.Linux,hostname.host1
         - $HOME/path/example.txt##os.Linux,hostname.host2

       If running on a Macbook named "host2", yadm will create a symbolic link
       which looks like this:

       $HOME/path/example.txt    ->    $HOME/path/example.txt##os.Darwin,host‐
       name.host2

       However, on another Mackbook named "host3", yadm will create a symbolic
       link which looks like this:

       $HOME/path/example.txt -> $HOME/path/example.txt##os.Darwin

       Since  the  hostname  doesn't  match any of the managed files, the more
       generic version is chosen.

       If running on a Linux server named "host4", the link will be:

       $HOME/path/example.txt -> $HOME/path/example.txt##os.Linux

       If running on a Solaris server, the link will use the default version:

       $HOME/path/example.txt -> $HOME/path/example.txt##default

       If running on a system, with class set to "Work", the link will be:

       $HOME/path/example.txt -> $HOME/path/example.txt##class.Work

       If no "##default" version exists and no files  have  valid  conditions,
       then no link will be created.

       Links  are also created for directories named this way, as long as they
       have at least one yadm managed file within them (at the top level).

       yadm will automatically create these links by default. This can be dis‐
       abled  using  the yadm.auto-alt configuration.  Even if disabled, links
       can be manually created by running yadm alt.

       Class is a special value which is stored locally on each  host  (inside
       the  local repository). To use alternate symlinks using class, you must
       set the value of class using the configuration  local.class.   This  is
       set like any other yadm configuration with the yadm config command. The
       following sets the class to be "Work".

         yadm config local.class Work

       Similarly, the values of architecture, os, hostname, and  user  can  be
       manually  overridden  using  the  configuration options local.arch, lo‐
       cal.os, local.hostname, and local.user.


## TEMPLATES
       If a template condition is defined in an alternate file's "##"  suffix,
       and the necessary dependencies for the template are available, then the
       file will be processed to create or overwrite files.

       Supported template processors:

       default
              This is yadm's built-in template processor.  This  processor  is
              very basic, with a Jinja-like syntax. The advantage of this pro‐
              cessor is that it only depends upon awk, which is  available  on
              most  *nix  systems. To use this processor, specify the value of
              "default" or just leave the value off (e.g. "##template").

       ESH    ESH is a template processor written in POSIX compliant shell. It
              allows  executing  shell  commands within templates. This can be
              used to reference your own configurations within templates,  for
              example:

                <% yadm config mysection.myconfig %>

              To use the ESH template processor, specify the value of "esh"

       j2cli  To  use the j2cli Jinja template processor, specify the value of
              "j2"  or "j2cli".

       envtpl To use the envtpl Jinja template processor, specify the value of
              "j2" or "envtpl".

       NOTE: Specifying "j2" as the processor will attempt to use j2cli or en‐
       vtpl, whichever is available.

       If the template processor specified is  available,  templates  will  be
       processed to create or overwrite files.

       During  processing,  the  following variables are available in the tem‐
       plate:

        Default              Jinja or ESH         Description
        -------------        -------------        ----------------------------
        yadm.arch            YADM_ARCH            uname -m
        yadm.class           YADM_CLASS           Last locally defined class
        yadm.classes         YADM_CLASSES         All classes
        yadm.distro          YADM_DISTRO          lsb_release -si
        yadm.distro_family   YADM_DISTRO_FAMILY   ID_LIKE from /etc/os-release
        yadm.hostname        YADM_HOSTNAME        uname -n (without domain)
        yadm.os              YADM_OS              uname -s
        yadm.source          YADM_SOURCE          Template filename
        yadm.user            YADM_USER            id -u -n
        env.VAR                                   Environment variable VAR

       NOTE: The OS for "Windows Subsystem for Linux" is  reported  as  "WSL",
       even though uname identifies as "Linux".

       NOTE:  If lsb_release is not available, DISTRO will be the ID specified
       in /etc/os-release.

       Examples:

       whatever##template with the following content

         {% if yadm.user == "harvey" %}
         config={{yadm.class}}-{{yadm.os}}
         {% else %}
         config=dev-whatever
         {% include "whatever.extra" %}
         {% endif %}

       would output a file named whatever with the following  content  if  the
       user is "harvey":

         config=work-Linux

       and the following otherwise (if whatever.extra contains admin=false):

         config=dev-whatever
         admin=false

       An  equivalent  Jinja  template  named whatever##template.j2 would look
       like:

         {% if YADM_USER == 'harvey' -%}
         config={{YADM_CLASS}}-{{YADM_OS}}
         {% else -%}
         config=dev-whatever
         {% include 'whatever.extra' %}
         {% endif -%}

       An equivalent ESH templated  named  whatever##template.esh  would  look
       like:

         <% if [ "$YADM_USER" = "harvey" ]; then -%>
         config=<%= $YADM_CLASS %>-<%= $YADM_OS %>
         <% else -%>
         config=dev-whatever
         <%+ whatever.extra %>
         <% fi -%>


## ENCRYPTION
       It  can  be  useful to manage confidential files, like SSH or GPG keys,
       across multiple systems. However, doing so would put  plain  text  data
       into a Git repository, which often resides on a public system. yadm can
       make it easy to encrypt and decrypt a set of  files  so  the  encrypted
       version  can  be  maintained  in the Git repository.  This feature will
       only work if a supported tool is available.  Both gpg(1) and openssl(1)
       are  supported.   gpg is used by default, but openssl can be configured
       with the yadm.cipher configuration.

       To use this feature, a list of patterns must be created  and  saved  as
       $HOME/.config/yadm/encrypt.   This  list of patterns should be relative
       to the configured work-tree (usually $HOME).  For example:

                  .ssh/*.key
                  .gnupg/*.gpg

       Standard filename expansions (*, ?, [) are supported.  If you have Bash
       version  4,  you may use "**" to match all subdirectories.  Other shell
       expansions like brace and tilde are not supported.  Spaces in paths are
       supported,  and should not be quoted.  If a directory is specified, its
       contents will be included, but not recursively.  Paths beginning with a
       "!" will be excluded.

       The yadm encrypt command will find all files matching the patterns, and
       prompt for a password. Once a  password  has  confirmed,  the  matching
       files  will  be encrypted and saved as $HOME/.local/share/yadm/archive.
       The "encrypt" and "archive" files should be added to the  yadm  reposi‐
       tory so they are available across multiple systems.

       To decrypt these files later, or on another system run yadm decrypt and
       provide the correct password.  After files are  decrypted,  permissions
       are automatically updated as described in the PERMISSIONS section.

       Symmetric  encryption is used by default, but asymmetric encryption may
       be enabled using the yadm.gpg-recipient configuration.

       NOTE: It is recommended that you use a private repository when  keeping
       confidential files, even though they are encrypted.

       Patterns found in $HOME/.config/yadm/encrypt are automatically added to
       the repository's info/exclude file every  time  yadm  encrypt  is  run.
       This is to prevent accidentally committing sensitive data to the repos‐
       itory.  This can be disabled using the yadm.auto-exclude configuration.

       Using transcrypt or git-crypt

       A completely separate option for encrypting data is to install and  use
       transcrypt  or  git-crypt.   Once installed, you can use these tools by
       running yadm transcrypt or yadm git-crypt.  These tools enables  trans‐
       parent  encryption and decryption of files in a git repository. See the
       following web sites for more information:

       - https://github.com/elasticdog/transcrypt

       - https://github.com/AGWA/git-crypt

## PERMISSIONS
       When files are checked out of a Git repository, their  initial  permis‐
       sions  are  dependent upon the user's umask. Because of this, yadm will
       automatically update the permissions of some file  paths.  The  "group"
       and "others" permissions will be removed from the following files:

       - $HOME/.local/share/yadm/archive

       - All files matching patterns in $HOME/.config/yadm/encrypt

       - The SSH directory and files, .ssh/*

       - The GPG directory and files, .gnupg/*

       yadm will automatically update permissions by default. This can be dis‐
       abled using the yadm.auto-perms configuration. Even if  disabled,  per‐
       missions  can  be manually updated by running yadm perms.  The .ssh di‐
       rectory processing can be disabled using the yadm.ssh-perms  configura‐
       tion.  The  .gnupg  directory  processing  can  be  disabled  using the
       yadm.gpg-perms configuration.

       When cloning a repo which includes data in a .ssh or .gnupg  directory,
       if  those  directories  do  not exist at the time of cloning, yadm will
       create the directories with mask 0700 prior to merging the fetched data
       into the work-tree.

       When running a Git command and .ssh or .gnupg directories do not exist,
       yadm will create those directories with mask 0700 prior to running  the
       Git command. This can be disabled using the yadm.auto-private-dirs con‐
       figuration.


## HOOKS
       For every command yadm supports, a program can be provided to  run  be‐
       fore  or  after  that  command.  These are referred to as "hooks". yadm
       looks for hooks in the directory $HOME/.config/yadm/hooks.   Each  hook
       is named using a prefix of pre_ or post_, followed by the command which
       should trigger the hook. For example, to create a hook which is run af‐
       ter every yadm pull command, create a hook named post_pull.  Hooks must
       have the executable file permission set.

       If a pre_ hook is defined, and the hook terminates with a non-zero exit
       status,  yadm  will  refuse  to run the yadm command. For example, if a
       pre_commit hook is defined, but that command ends with a non-zero  exit
       status,  the  yadm commit will never be run. This allows one to "short-
       circuit" any operation using a pre_ hook.

       Hooks have the following environment variables  available  to  them  at
       runtime:

       YADM_HOOK_COMMAND
              The command which triggered the hook

       YADM_HOOK_EXIT
              The exit status of the yadm command

       YADM_HOOK_FULL_COMMAND
              The yadm command with all command line arguments (parameters are
              space delimited, and any space, tab or backslash will be escaped
              with a backslash)

       YADM_HOOK_REPO
              The path to the yadm repository

       YADM_HOOK_WORK
              The path to the work-tree


## FILES
       All  of  yadm's  configurations  are  relative to the "yadm directory".
       yadm uses the "XDG Base Directory Specification" to determine this  di‐
       rectory.   If the environment variable $XDG_CONFIG_HOME is defined as a
       fully qualified path, this  directory  will  be  $XDG_CONFIG_HOME/yadm.
       Otherwise it will be $HOME/.config/yadm.

       Similarly, yadm's data files are relative to the "yadm data directory".
       yadm uses the "XDG Base Directory Specification" to determine this  di‐
       rectory.   If  the  environment variable $XDG_DATA_HOME is defined as a
       fully qualified path, this directory will be $XDG_DATA_HOME/yadm.  Oth‐
       erwise it will be $HOME/.local/share/yadm.

       The  following  are the default paths yadm uses for its own data.  Most
       of these paths can be altered using universal options.  See the OPTIONS
       section for details.

       $HOME/.config/yadm
              The yadm directory. By default, all configs yadm stores is rela‐
              tive to this directory.

       $HOME/.local/share/yadm
              The yadm data directory. By default, all  data  yadm  stores  is
              relative to this directory.

       $YADM_DIR/config
              Configuration file for yadm.

       $YADM_DIR/alt
              This  is  a  directory  to keep "alternate files" without having
              them side-by-side with the resulting symlink or  processed  tem‐
              plate.  Alternate files placed in this directory will be created
              relative to $HOME instead.

       $YADM_DATA/repo.git
              Git repository used by yadm.

       $YADM_DIR/encrypt
              List of globs used for encrypt/decrypt

       $YADM_DATA/archive
              All files encrypted with yadm encrypt are stored in this file.


## EXAMPLES
       yadm init
              Create an empty repo for managing files

       yadm add .bash_profile ; yadm commit
              Add .bash_profile to the Git index and create a new commit

       yadm remote add origin <url>
              Add a remote origin to an existing repository

       yadm push -u origin master
              Initial push of master to origin

       echo .ssh/*.key >> $HOME/.config/yadm/encrypt
              Add a new pattern to the list of encrypted files

       yadm encrypt ; yadm add ~/.local/share/yadm/archive ; yadm commit
              Commit a new set of encrypted files
