#
# Creates detached ascii signatures and md5 hashes for each of the files in the
# current directory.
#
# Also verifies the signatures.
#
# For each file in the current directory, two new files are created:
#
#   <name>.asc -- ascii-armored detached PGP digital signature
#   <name>.md5 -- md5 hash (checksum)
#
# where <name> is the name of the file, not including file path.  
# 
# For example, foo-1.0-src.tar.gz in the current directory will result in 
# foo-1.0-src.tar.gz.asc and foo-1.0-src.tar.gz.md5 added to the current 
# directory. 
#
# Deletes any .asc or .md5 files in the current directory before processing
# and does NOT recurse subdirectories.
#
# Assumes that you have a pgp id and keypair set up and prompts for the 
# passphrase for each signature created.
#
# usage:
#     sign_and_hash.sh
#
# requires:
#    gpg
#    md5sum
