	A quickie solution that would go part of the way is to have
a shell script wrapper that would work off of file name extensions:

#! /bin/csh -f
#
#       cvt_fmt
if ($#argv != 2) then
        cat << +++
usage: cvt_fmt file fmt_to_convert_to
example: "cvt_fmt foo.xbm rast" would give a "foo.rast" file
+++
else
        set source=$1
        set dest=$2
        ${source:e}topbm $source | pbmto${dest} > ${source:r}.$dest
endif

	add cases for color and graymap and additional seasoning to
taste :-)
