"File:        vala.vim
"Description: Syntax checking plugin for syntastic.vim
"Maintainer:  Konstantin Stepanov (me@kstep.me)
"Notes:       Add special comment line into your vala file starting with
"             "// modules: " and containing space delimited list of vala
"             modules, used by the file, so this script can build correct
"             --pkg arguments.
"             Add another special comment line into your vala file starting
"             with "// vapidirs: " followed by a space delimited list of
"             the vapi directories so this script can build with the correct
"             --vapidir arguments
"             Alternatively you can set the g:syntastic_vala_modules array
"             and/or the g:syntastic_vala_vapidirs array
"             in your .vimrc or .lvimrc with localvimrc plugin
"             (http://www.vim.org/scripts/script.php?script_id=441).
"             Valac compiler is not the fastest thing in the world, so you
"             may want to disable this plugin with
"             let g:syntastic_vala_check_disabled = 1 command in your .vimrc or
"             command line. Unlet this variable to set it to 0 to reenable
"             this checker.
