truclean

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)
