" Comments:
" -- started from Matlab indent file in vim 6.0
" -- Many people like a 4 blank indentation, I prefer 2 blanks: this can
" be adjusted by setting `GAPIndentShift' to 4, 2 (default) or whatever
" you like
" TODO: nice handling of `continuation' lines
" Only load this indent file when no other was loaded.
