+`basename $0`: Builds the Fuel@OPNFV stack
+
+usage: `basename $0` [-s spec-file] [-c cache-URI] [-l log-file] [-f flags]
+ [output-directory]
+
+OPTIONS:
+ -s spec-file (NOTE! DEPRECATED!)
+ define the build-spec file, default ../build/config.mk. The script only
+ verifies that the spec-file exists.
+ -c cache base URI
+ specifies the base URI to a build cache to be used/updated, supported
+ methods are http://, ftp:// and file://
+ -l log-file
+ specifies the output log-file (stdout and stderr), if not specified
+ logs are output to console as normal
+ -v
+ version tag to be applied to the build result
+ -r
+ alternative remote access method script/program. curl is default.
+ -f flag[...]
+ build flags:
+ s: Do nothing, succeed
+ f: Do nothing, fail
+ D: Debug mode
+ P: Clear the local cache before building. This flag is only
+ valid if the "-c cache-URI" options has been specified and
+ and the method in the cache-URI is file:// (local cache).
+
+ -h help, prints this help text
+
+ output-directory, specifies the directory for the output artifacts
+ (.iso file). If no output-directory is specified, the current path
+ when calling the script is used.
+
+
+Description:
+
+build.sh builds the opnfv .iso artifact.
+To reduce build time it uses build caches on a local or remote location. A
+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 and set
+ to the method file:// , if -c is
+ not provided the cache will stay local.
+2) If a cache is invalidated by the make system - the exact logic is encoded
+ in the cache.mk of the different parts of the build.
+3) A valid cache does not exist on the specified -c cache-base-URI.
+
+A cache has a blob (binary data) and a meta file in the format of:
+ <SHA1>.blob
+ <SHA1>.meta
+
+Logging is 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)
+ - 101 Build system instance busy
+ - 200 Build failure
+
+Examples:
+ build -c http://opnfv.org/artifactory/fuel/cache \
+ -d ~/jenkins/genesis/fuel/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!
