# Usage: $progname [OPTION]... [--] to-address...
#
# -C ADDR --carbon-copy=ADDR send a carbon-copy to ADDR
# -F ADDR --from=ADDR override default from address with ADDR
# -f FILE --filename=FILE content of this part
# -m TYPE --mime-type=TYPE mime-type of this part
# -n another mime part (-f, -m) to follow
# -o FILE --output-file=FILE output to FILE instead of sending
# -s TEXT --subject=TEXT set subject header
# -v --verbose run in verbose mode
# --version print version information
# -h,-? --help print short or long help message
# Assemble a (possibly multi-part) mime message and hand it to the local
# sendmail for onward delivery. MUAs tend to mangle patch attachments in
# various ways: not setting the mime-type correctly, line wrapping the
# patch itself, escaping certain values, etc. This script is designed to
# make it easier to send a patch as a MIME attachment, though it is general
# enough that it might be useful otherwise.
# For example to send a patch as an attachment, assuming the patch itself
# is in PATCHFILE:
#
# echo 'Applied to HEAD' > body
# $progname -f body -m text/plain -n -f PATCHFILE -m text/x-patch \
# -s 'FYI: PATCHFILE' patch-list@foo.org
# You will probably find using this script in conjunction with clcommit
# or cvsapply will save you an awful lot of typing.
# Report bugs to <gary@gnu.org>
