sublimetext2 - Sublime Text 2 - writing a script to process multimarkdown -

there excellent package preview markdown written using sublime text. wanted know how might modify it, or perhaps use basis writing 1 process multi-markdown.

i'm using linux (ubuntu) , i'm calling multimarkdown in terminal on each file.

one of issues think might face multimarkdown refuses parse open file reason.

any thoughts on how might begin or if alternative solution exists gratefully received.

there multimarkdown option in syntax list - view > syntax > markdown > multimarkdown. isn't working? way syntax (and other) files in packages folder of sublime text 2. syntax file:

/users/[username]/library/application support/sublime text 2/packages/markdown/markdown.tmlanguage 

and multimarkdown file in same directory.
