Subject: [PATCH] Add script o generate the cgcs-centos-repo folder and mock
 config file.

The build system needs the cgcs-centos-repo symlinks pointing to
the files in the mirror. Also, the mock.cfg.proto file is needed
to provide configurations to the mock environment.

With this script we eliminate the need of having a separate
repository just to hold these symlinks. Now, the developers can
recreate this folder whenever is needed.

+### To generate cgcs-centos-repo
+
+The cgcs-centos-repo is a set of symbolic links to the packages in the mirror
+and the mock configuration file. It is needed to create these links if this is
+the first build or the mirror has been updated.
+
+```
+cd $MY_REPO_ROOT_DIR/stx-tools/scripts
+./generate-cgcs-centos-repo.sh /import/mirror/CentOS/pike
+```
+
+Where the argument to the script is the path of the mirror.
+
+
 ### To build all packages:
 ```
 $ cd $MY_REPO
