###
### This script executes a different action for each file type
### specified.  It tries to match the second parameter against the
### patterns specified in the 'case' statement (see below).
###
### If you want to add new file types & actions to this script, just
### add a new entry to the 'case' statement *before* the last one
### ( *) ... )
###
### For greater flexibility, gitaction's first parameter is the name
### of the directory where the file resides.  The complete file name
### is obtained by appending the file base name to the file path:
### "$1/$2".
###
### If you enhance this script, please send me a patch at
### gnuit-dev@gnu.org.  I'll include it in the next release.
###

###
### Instead of hardcoding `more' or `less' here, we can use GNUIT_PAGER,
### a shell environment variable that is bound on one of them, depending
### on your environment.  The default is to call `more', but you can
### change GNUIT_PAGER to point to your favorite pager...
###

###
### Thanks to John Stump for suggesting me to get rid of gitmatch.
### Thanks to Juhapekka Tolvanen <juhtolv@silmu.st.jyu.fi> for the new
### mikmod-related entries.
###

###
### Note: Not all the programs called here are able to handle the --
### command line switch.  These are:
###   emacs lynx elinks ar btshowmetainfo html2text lha pstotext tar w3m
###   xli xloadimage zoo jar avifile-player xchm iceweasel firefox gv
###   sensible-browser kfax xdvi ted unrtf dotty fbgs gm xcfview sqlite
###   gm xfmedia uncompress djview djview3 javap lyx vrweb metamail
### programs with multiple implementations that we can't rely on supporting --:
###    file last more ldd nroff cpio uudecode objdump tar ar uncompress
### There are some that I couldn't test.
###
### When these programs will be fixed, we should add -- to them...
### Until then, we will fail to run commands like `xfig -P -P' to
### process a file called `-P'.
