+  -l log-file ($BUILD_LOG), specifies the output log-file (stdout and stderr), if not specified logs are output to console as normal

+
+Description:
+build.sh builds opnfv .iso artifact.
+To reduce build time it uses build cache on a local or remote location. The cache is rebuilt and uploaded if either of the below conditions are met:
+1) The P(opulate) flag is set and the -c cache-base-URI is provided, if -c is not provided the cache will stay local.
+2) If the cache is invalidated by one of the following conditions:
+   - The config spec md5sum does not compare to the md5sum for the spec which the cache was built.
+   - The git Commit-Id on the remote repos/HEAD defined in the spec file does not correspont with the Commit-Id for what the cache was built with.
+3) A valid cache does not exist on the specified -c cache-base-URI.
+
+The cache URI object name is foreman_cache-"md5sum(spec file)"
+
+Logging by default to console, but can be directed elsewhere with the -l option in which case both stdout and stderr is redirected to that destination.
+
+Built in unit testing of components is enabled by adding the t(est) flag.
+
+Return codes:
+ - 0 Success!
+ - 1-99 Unspecified build error
+ - 100-199 Build system internal error (not build it self)
+   o 101 Build system instance busy
+ - 200 Build failure
+
+Examples:
+build -c http://opnfv.org/artifactory/foreman/cache -d ~/jenkins/genesis/foreman/ci/output -f ti
+NOTE: At current the build scope is set to the git root of the repository, -d destination locations outside that scope will not work
