This little script sends an email with one or more attachments from the commandline. It uses either Perl's MIME:Base64 or openssl to do the Base64 encoding.

# Sends an email with attachements need perl with MIME::Base64

#Your base64 encoder - must accept STDIN and encode to STDOUT
#BASE64="eval openssl enc -base64"
BASE64="perl -e \"use MIME::Base64; print encode_base64(join('',<STDIN>));\""
