A small script that makes Ed2K links for use with the eDonkey P2P network. Just pass the script a filename as an argument, and the Ed2K link is printed to STDOUT. Uses Digest::MD5.
MASSIVE UPDATE: I pretty much rewrote the script from scratch and added a bunch of stuff: the ability to be used as both a commandline tool AND a GUI tool, the ability to hash multiple files, and some minor bugfixes. If you want to use the GUI, you must have Tk installed.

#
# Creates a "hash" link for use with the
# eDonkey2000 network, and prints it to
# STDOUT. Works as both a commandline tool
# and as a GUI tool. If the script is passed
# a list of filenames as arguments, it will
# print a link for each file to STDOUT.
# If the script is run with NO arguments,
# it starts in GUI mode. A Tk dialog will
# pop up and ask for a filename. The file's
# Ed2K link is printed to STDOUT.
#
# Usage:
#
# COMMANDLINE MODE
# $ perl ed2k_hash.pl myfile.zip other_file.zip thisfile.zip > finishe
+d_hash.txt
#
# GUI MODE
# $ perl ed2k_hash.pl
#
