The source files to be read by the different grammar tools (e.g. pp and sif ) must all start by giving a specification of the fragment form (similar to grammar specifications and pretty-printer specifications).
The fragment form syntax for source files is:
-- name: category: grammar --
where grammar be the name for the grammar for this source file. Category must be the name of a construction nonterminal in the grammar, and finally name is the name chosen for this fragment form (mostly not significant). If ': grammar' is omitted, the BETA grammar is assumed.
Please note, that it is important that category is the name of a construction nonterminal, i.e. a nonterminal specified by a construction rule:
category ::= ...;
