=head1 NAME
t/codingstd/filenames.t - checks that filenames conform to standards
# test all files
% prove t/codingstd/filenames.t
# test specific files
% perl t/codingstd/filenames.t src/foo.c include/parrot/bar.h
Checks that the filenames used for files within the Parrot distribution
conform to a set of highly portable standards.
=over 4
=item No multiple dots within filenames
Files with more than one dot ( '.' ) in their filename are problematic on
some platforms (e.g. VMS) hence avoid these in Parrot.
=item No strange characters in filenames
Filenames are restricted to the characters C<a-zA-Z0-9_-.>
=item Filenames length restriction
Filenames are restricted to 32 characters.
