# perl script to convert mbox file to files in a new MH directory
|
|
# aka another mbox -> MH conversion tool

|
|
# Fixed (hopefully) to account for From lines
|
|
# that are of various length and that might have
|
|
# time zone info at the end
|
|
# 20 January 2004

# Note: Running this with the -w flag generates the following warnings:
|
|
# Scalar value @word[1] better written as $word[1] at /path/to/convert_mbox.pl line 54
|
|
# Scalar value @word[0] better written as $word[1] at /path/to/convert_mbox.pl line 56
|
|
# Making these changes requires further changes in the script
|
|
# that results in much longer run-times.
