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.
The world is drowning in individual music files astray with corrupt
metadata, insignificant file names, and no way to identify the
music.
MusicDNS and the Open Fingerprint Architecture provide a system
for identifying a piece of music with nothing more than the sound
of the piece itself.
MusicDNS is the largest single dataset of acoustic fingerprints in
the world with more than 16 million individual tracks identified
and growing DAILY! With the Open Fingerprint client-code, tracks
can be identified consistently against the MusicDNS dataset, and
new tracks are easily added.
The Open Fingerprint is deployed world-wide--and now the client
source code is available under Open Source license.
Use the fingerprint code freely, or hook it up to the largest
repository of fingerprinted tracks on the planet--MusicDNS. Free
client keys for developers and non-profits are available on the
website. For commercial deployment, use the low-cost MusicDNS.com
service from MusicIP.
