Add configuration.ccl "REQUIRES" information to the auto-generated ThornList

Issue #2269 closed

Currently, the ThornList auto-generated with a new Cactus configuration displays information on how each thorn interacts with/depends on others, based on the content of the thorn’s param.ccl & interface.ccl. I suggest adding the “REQUIRES” information from the thorn’s configuration.ccl to this displayed summary.

I’ve made simple modifications to two Perl scripts in Cactus/lib/sbin that appear to do this satisfactorily. I’d appreciate an evaluation and application to the ETK. For variety, I’ve put the new information in angle brackets <>, but this is obviously an aesthetic choice.

    Apparently the syntax described for the configuration.ccl files in the UserGuide is not what the parsers actually support. Namely:

    • there is a “REQUIRES THORNS foo bar” line
    • REQUIRES actually takes multiple entries separated by whitespace

    Examples can be obtained from grep -i requires arrangements/*/*/configuration.ccl.
