" Description: Better syntax highlighting for Objective-C files (part of the
" cocoa.vim plugin).
" Last Updated: June 23, 2009
" NOTE: This next file (cocoa_keywords.vim) is rather large and may slow
" things down. Loading it seems to take less than 0.5 microseconds
" on my machine, but I'm not sure of the consequences; if it is slow
" for you, just comment out the next line.
