${release_script} - The Linaro GCC snapshot, and release script.

usage
echo -e "\
${bold}DESCRIPTION${NC}"
echo -e "\
\"${release_script}\" is a utility that is used to create tarballs
and branches for Linaro toolchain GCC monthly snapshots, quarterly
releases.
By default ${release_script} creates a snapshot tarball, branch,
and tag.
${bold}REMOTES${NC}
${release_script} attempts to be intelligent (and slightly permissive)
about handling git remote naming. Its ability to do so is complicated
by how the Linaro git mirror is set-up.
Linaro maintains a mirror of the upstream FSF git repository in order
to locally stage backports, store snapshot and release branches, and store
snapshot, release candidate, and release tags.
The Linaro GCC mirror includes a writeable ${bold}linaro-local/${NC} namespace
that is not present on the upstream FSF git repository.
The following, Linaro only, writable namespaces are used for storing
Linaro snapshot and release branches, respectively:
${bold}linaro-local/snapshots/${NC}
${bold}linaro-local/releases/${NC}
Linaro provides read-only access to the Linaro GCC mirror via ${italic}gitolite${NC}
and read-write access (only to the linaro-local/* namespace) via ${italic}gerrit${NC}.
Here is the recommended setup of the gcc git repository:
1) Clone the read-only gitolite repository as 'origin':
git clone https://git.linaro.org/toolchain/gcc.git gcc.git
${italic}${bold}Note: ${NC}${italic} If you would like use a remote name other than 'origin' run
the following command and then replace 'origin' in the examples with
your desired remote name.${NC}
git remote rename origin ${italic}<remote>${NC}
2) Set the pushurl for the default remote as the gerrit server:
git config remote.origin.pushurl \\
ssh://review.linaro.org:29418/toolchain/gcc
3) Set the gerrit username:
${italic}${bold}Note: ${NC}${italic}To find your gerrit username look on: review.linaro.org
-> [User Name] -> Settings -> username
git config remote.origin.username ${italic}<Linaro gerrit username>${NC}
This is an example of what .git/config will look like for remote
'origin' after setting up the repository:
[remote "origin"]
url = https://git.linaro.org/toolchain/gcc.git
fetch = +refs/heads/*:refs/remotes/origin/*
pushurl = ssh://review.linaro.org:29418/toolchain/gcc
username = ryanarn
${bold}PRECONDITIONS${NC}
${release_script} needs to be executed in the top-level GCC source
directory.
The GCC source directory must be a git repository. This script will not
work on a GCC source tarball or a GCC SVN repository.
See the following subsection on ${bold}REMOTES${NC} for a
recommendation on how how to clone the GCC repository in a manner which
will allow pushing changes to the repository.
${bold}OPTIONS${NC}"
cat << EOF
-d DATE
Create DATE snapshot or release. The DATE may be in the
following formats: YYYY.MM, YYYY-MM, YYYY/MM, YYYY.MM.DD,
YYYY-MM-DD, YYYY/MM/DD. The Default is the current date.
-e REMOTE
This specifies the remote (as REMOTE) to use when
outputting the push instructions. NOTE: This script does
not actually push to the remotes.
It is necessary to designate an alternate FSF remote in
order to push tags and gcc/LINARO-VERSION updates to the
upstream branches for snapshots.
-h
Print this extended help text.
-R [SPIN]
This tells ${release_script} to create a release tarball,
branch and tag with an optional spin number SPIN. By
default no SPIN number is used. SPIN must be > 0 if
specified.
-S [SPIN]
[Default] This explicitly tells ${release_script} to create
a snapshot tarball, branch, and tag with an optional spin
number SPIN. By default no SPIN number is used. SPIN must
be > 0 if specified.
-r [RC] [SPIN]
This tells ${release_script} to create a release candidate
tarball, branch and tag with an optional release candidate
number RC and an optional spin number SPIN. By default RC
number '1' is used and SPIN is left blank/off. RC must be
>= 1. SPIN must be >= 1 if used. This option will append
"[-SPIN]-rcRC" on the end of the release string.
Note: If you want to specify a SPIN you MUST specify an RC
argument as well or ${release_script} will make the first
argument the RC value.
-t TRACK_REF
Derive (track) the snapshot, release, or release candidate
from tacked reference TRACK_REF. The default is to use the
existing branch and not use a tag.
-v
Emit verbose output. Use more than once to increase output
further.
-u
