= SIMP Build Tasks =

Use 'rake' and choose one of the options below that best suits your
needs. If you are simply trying to build the SIMP tarball, use the
'rake tar:build[:chroot]' option.

NOTE: Any task that requires a :chroot input will require you to be in
the 'mock' group and have the 'mock' package installed.

== Space Requirements ==

A full parallel build will take around 500M for each git submodule built.

If you are space limited, set SIMP_RAKE_LIMIT_CPUS=1 at build time.

== Environment Variables ==

* SIMP_RAKE_CHOWN_EVERYTHING=(Y|n)
- Chown everything to the 'mock' group prior to building

* SIMP_RAKE_MOCK_OFFLINE=(y|N)
- Mock runs are limited to the local cache

* SIMP_RAKE_LIMIT_CPUS=#
- Default: Num system CPUs - 1
- An Integer that limits builds to # processors
- If set to '1', will only build in a single mock directory

* SIMP_GIT_BRANCH=<Branch ID>
- If you are working in the supermodule and wish to perform a reset, but
  retain your working branch at the supermodule level. You can set this to
  ignore the current supermodule branch value.
- This is particularly valuable when using Jenkins.
