Comment (by Roland Haas):

I made a pull request with your patch, and some extra changes (https://bitbucket.org/cactuscode/cactus/pull-requests/61/parse-requires-and-requires-thorns-when/commits). See https://bitbucket.org/cactuscode/cactus/pull-requests/61/parse-requires-and-requires-thorns-when/diff

Please take a look and if you want to review as ok click on the Approve button.

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.
