| 26 # Commentary: | |
| 27 | |
| 28 # Inspired by a similar set of scripts by Charles Sandel <sandel@cli.com>, | |
| 29 # but generalized into this single script. | |
| 30 | |
| 31 # Front-end shell script for GNU Emacs, used to manage multiple versions of | |
| 32 # Emacs and its associated utilities. | |
| 33 # | |
| 34 # Strategy: Install this script as "$prefix/bin/[progname]", for each | |
| 35 # program named [progname], (e.g. "emacs", "ispell", "etags", etc). These | |
| 36 # are the commands users would normally execute to run them. | |
| 37 | |
| 38 # Give each version of emacs/xemacs/mule/ispell a separate hierarchy under | |
| 39 # $prefix/[emacs|xemacs|mule|ispell], with the name | |
| 40 # "[emacs|xemacs|mule|ispell]-NN.NN" where NN.NN is the version number. | |
| 41 # This script looks at what versions are available, and selects a version, | |
| 42 # currently whatever is specified by $DEFAULTLVERSION. | |
| 43 | |
| 44 # However, users can specify their own choice to force the selection of a | |
| 45 # particular version by setting the environment variable PROGNAMEVERSION | |
| 46 # (e.g. EMACSVERSION, MULEVERSION, XEMACSVERSION, etc.) to have a value | |
| 47 # which is the version number of the program that they want to use (just | |
| 48 # the numeric value), or to specify either the NEWEST or OLDEST versions. | |
| 49 | |
| 50 # Code: | |
| 51 | |
| 52 # Name by which this script was invoked. | |
