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.
Gamin is a file and directory monitoring system defined to be a subset
of the FAM (File Alteration Monitor) system.
The main goals of the project are:
1. Minimize the security model of FAM -- the daemon runs under the
user account.
2. Simplify the code base, dropping some of the most exotic features
of FAM.
3. Provide an API and ABI compatible replacement for FAM.
4. Try to fix some other issues like resource consumption.
This package provides the Gamin libraries.
