# Usage: $progname [OPTION]... [--] to-address...
#
#           --debug             enable verbose shell tracing
# -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>
