" File: objc#method_builder.vim (part of the cocoa.vim plugin)

" Description: Builds an empty implementation (*.m) file given a header (*.h)
" file. When called with no arguments (simply ":BuildMethods"),
" it looks for the corresponding header file of the current *.m
" file (e.g. "foo.m" -> "foo.h").
