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-
prompt for a password. Once a password has confirmed, the matching
files will be encrypted and saved as $HOME/.local/share/yadm/archive.

tory so they are available across multiple systems.

are automatically updated as described in the PERMISSIONS section.

For every command yadm supports, a program can be provided to run
before 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
after every yadm pull command, create a hook named post_pull. Hooks
should trigger the hook. For example, to create a hook which is run
after 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
