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 : ${TMPDIR=/tmp} : ${HOST=`hostname`} : ${MV="mv -f"} : ${RM="rm -f"} : ${SED="sed"} dirname="s,/[^/]*$,," basename="s,^.*/,,g" # Work around backward compatibility issue on IRIX 6.5.
