This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
MusicBrainz is a user-maintained community music metadatabase.
Music metadata is information such as the artist name, the release
title, and the list of tracks that appear on a release. MusicBrainz
collects this information about recordings and makes it available
to the public. All of the data in MusicBrainz is user contributed
and user maintained.
This library is an interface to the MusicBrainz database. It is
aimed at developers of media players, CD rippers, taggers and other
applications requiring music metadata. The service's architecture
follows the REST design principles. Interaction with the web service
is done using HTTP and all content is served in a simple but flexible
XML format.
