The iFix003 readme.txt file states, among other things, the following:

Run repotools-<app> -clean for each application that is installed to clear the repotools cache.
Note: This will also display the help output. For instance:
   - repotools-jts -clean
   - repotools-ccm -clean
   - repotools-qm -clean
   - repotools-rm -clean

Since pretty much everyone is conditioned to think he/she has done something wrong when seeing a usage statement (particularly one that goes on for pages!) after entering a command, I would suggest changing the instructions to read:

Run repotools-<app> -clean -version for each application that is installed to clear the repotools cache.
For instance:
   - repotools-jts -clean -version
   - repotools-ccm -clean -version
   - repotools-qm -clean -version
   - repotools-rm -clean -version

For one thing, this will dramatically shorten the command output :-)  For another, this will also give a visual cue that the patch one is trying to apply is active or not.

That said, what does the below "null" string refer to?

# ./repotools-jts.sh -clean -version
