""" Converts a directory full of .eml files to a single Unix "mbox" file.
Accepts as input either an individual .eml file or a directory containing one
or more .eml files.
The output mbox will be created if it doesn't already exist. If it exists,
it will be appended to. There is no checking for duplicates, so use caution.
If duplicate filtering is desired, it could be added to addFileToMbox().
Inspired by http://www.cosmicsoft.net/emlxconvert.html
Usage:
$ ./emlToMbox.py inputdir/ output.mbox
$ ./emlToMbox.py input.eml output.mbox
Requires Python 2.5 or later
STATUS: Tested and appears to work.
