3 "Description: Syntax checking plugin for syntastic.vim
4 "Maintainer: Konstantin Stepanov (me@kstep.me)
5 "Notes: Add special comment line into your vala file starting with
6 " "// modules: " and containing space delimited list of vala
7 " modules, used by the file, so this script can build correct
8 " --pkg arguments.
9 " Valac compiler is not the fastest thing in the world, so you
10 " may want to disable this plugin with
11 " let g:syntastic_vala_check_disabled = 1 command in your .vimrc or
12 " command line. Unlet this variable to set it to 0 to reenable
13 " this checker.
