Subject: HG to MH mail conversion

 I have developed a convenient way to convert hg format mail files back to
the original unix format mail files, which mh can read.   The shell script,
convert-hg, is given below, along with two files that it references.

 Note: if you used hg to classify mail and you want to retain this
classification, copy the file convert-hg-script and replace the line
containing the list all command to a sequence of list commands, one
for each class, writing to separate mail files.  You'll also have to modify
the shell script convert-hg.  You can then read these separate mail files
into different mh folders.

 This software is provided as a public service.  Although I have
tested it, no guarantee of its usefulness for any purpose is intended.
Any damage or loss that using this software causes is the sole problem
of the user.


APPENDIX A: convert-hg (shell script)

#! /bin/csh -f
# NAME convert-hg
# SYNOPSIS convert-hg [ message-file ]
# DESCRIPTION Converts hg format mail files to standard unix format mail files.
#             Input is message-file if supplied or else ~/mail.hg. Output is
#             to standard output.  To convert this mail to mh, you can use
#             the mh command:
#                    inc -file name
#             (where name is the file containing the unix format mail)
# FILES
#  This shell script references convert-hg-script and convert-hg.sed, which
#  are expected to be located in the current working directory.
