vifn - edit by function name rather than file name, uses vi
vifn [filename/]function-name [...]
vifn is a crude script which uses output from pmccabe(1) to allow
editing by function name rather than file name. When duplicate function names
exist in more than one file, vifn cycles through each one. Use
filename/ when multiple files contain identically-named functions and
you know the one you want.
vifn uses the file "pmccabe.out" in the current directory, or
creates it if not found by running pmccabe on files in the current
directory. Maybe this isn't really a bug, but it could be better.
vifn does not use the $EDITOR environment variable only
because there are editors which misunderstand vi's +line
convention for starting the editor positioned at a specific line.
