In case you want to have proper syntax highlighting:


For mltk module files, in .vimrc:
au BufRead,BufNewFile *.build set filetype=sh
au BufRead,BufNewFile *.conf set filetype=sh
au BufRead,BufNewFile *.conf.* set filetype=sh
au BufRead,BufNewFile *.inc set filetype=sh
au BufRead,BufNewFile *.include set filetype=sh


For #!/bin/ash in scripts, create .vim/scripts.vim:
if did_filetype()
	finish
endif

if getline(1) =~# '^#!.*/ash'
	setf sh
endif
