"
|

" To enable folding put in your vimrc:
|
||||
" set foldenable
|
||||
"
|
||||
" Folding will make only one fold for a complete function, even though it has
|
||||
" more than one function head and body.
|
||||
"
|
||||
" To change this behaviour put in your vimrc file:
|
||||
" let g:erlangFoldSplitFunction=1
