+Performs a 'clean' build step, based on the releaseables information, i.e. the
+list of artifacts produced during a PDK build.
+This cleaning step ensures all the build artifacts produced by the build are
+actually removed even if the source code has changed since the PDK build. 
+
+Usage: truclean.pl -p PACKAGE_EXPR [-r RELEASABLES_DIR] [-d]
+
+Options:
+  -h, --help            Show this help message and exit
+  -p PACKAGE_EXPR       Clean (remove) build artifacts belonging to the package
+                        or packages indicated by PACKAGE_EXPR.
+                        PACKAGE_EXPR is the path (wildcards allowed) of the
+                        package, e.g. 'sf/app/camera' or 'sf/mw/*' or '*/*/*'.
+                        If the first directory level is not specified then 'sf'
+                        is assumed. 
+  -r RELEASABLES_DIR    Use RELEASEABLES_DIR as root of the releaseable files
+                        (default is $RELEASEABLES_DIR_DEFAULT).
+  -d                    Dry run (Do not remove files for real)
