Changeset 66 in text-formbuilder for trunk/lib/Text/FormBuilder/grammar

Timestamp:

Author:

Message:

worked on the rules for parsing lists in the grammar
allow end of field line comments
growable fields can specify a limit; e.g. "person*4" to limit to 4
use '+other' to specify that a field should have an 'Other' option (FB 3.02)
rearranged TODOs in the main documentation
