Usage: $CMD [-h] [-o output_dir] [-m msg_body_file] [-s subject] [-r relative_to] [-i commit_id] -u remote -b branch
-b branch Branch name in the specified remote
-c Create an RFC (Request for Comment) patch series
-h Display this help message
-i commit_id Ending commit (default: HEAD)
-m msg_body_file The file containing a blurb to be inserted into the summary email
-o output_dir Specify the output directory for the messages (default: pull-PID)
-p prefix Use [prefix N/M] instead of [PATCH N/M] as the subject prefix
-r relative_to Starting commit (default: master)
-s subject The subject to be inserted into the summary email
-u remote The git remote where the branch is located
Examples:
$CMD -u contrib -b nitin/basic
$CMD -u contrib -r distro/master -i nitin/distro -b nitin/distro
