11 " There are three sets of highlighting in here:
12 " One is "erlang_characters", second is "erlang_functions" and third
13 " is "erlang_keywords".
14 " If you want to disable keywords highlighting, put in your .vimrc:
15 " let erlang_keywords=1
16 " If you want to disable erlang BIF highlighting, put in your .vimrc
18 " let erlang_functions=1
19 " If you want to disable special characters highlighting, put in
21 " let erlang_characters=1
24 " For version 5.x: Clear all syntax items
25 " For version 6.x: Quit when a syntax file was already loaded
