The parrot packages with libparrot0 and libparrot-devel,
plus parrot-perl6 and parrot-languages are updated to 0.7.0-1 for
the Cygwin distribution.
This release fixes some minor issues with the languages, but m4 was
removed, pipp, tcl, forth and pheme still do not work.
Parrot is a virtual machine designed to efficiently compile and
execute bytecode for interpreted languages.
Parrot is a target for the upcoming Perl 6 and a lot of other
languages.
