Log message:
Simply and speed up buildlink3.mk files and processing.
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.

Log message:
Improve COMMENT and DESCRiptions.
No longer identical.
Don't say Linux since this is for other platforms too.
Don't mention GUI interface in the description for the console package.

By the way, the gtk version is really GNOME, but upstreams calls it gtk.

Log message:
Add DESTDIR support.

update to 0.9.6
changes:
-Use Lambert W to solve more equations and avoid infinite loop when solving
 some equations
-More data on elements
-Fix simplification of (1-1/x)^3 and similar
-Fix clumsy mistakes in with prefixes leading to crashes
-Fix parsing of unit expressions (when converting) such as W/(m K)
-Add more exact values for sin() and cos() and avoid floating point underflow
 by, in approximate mode, checking against the value of pi
-Always input decimal separator sign on keypad separator press
-Fix crash when expression entry reclaims focus if compiled with optimizations
 (GTK+)
-New units: typographic units, pouce, pied du roi, grams of TNT and tons of TNT
-New functions: lambertW(), addDays(), addMonths(), addYear(), addTime(),
 isNumber(), isReal(), isRational(), isInteger(), representsNumber(),
 representsReal(), representsRational(), representsInteger()
-New variable: omega constant
-Other minor fixes and enhancements

also fix wrong inclusion of scrollkeeper/bl3

Log message:
Change the format of BUILDLINK_ORDER to contain depth information as well,
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.

For example, "make show-buildlink3" in fonts/Xft2 displays:

	zlib
	fontconfig
	    iconv
	    zlib
	    freetype2
	    expat
	freetype2
	Xrender
	    renderproto

Log message:
Track information in a new variable BUILDLINK_ORDER that informs us
of the order in which buildlink3.mk files are (recursively) included
by a package Makefile.

Log message:
Sweep pkgsrc and convert packages that included intltool/buildlink3.mk
to use instead "USE_TOOLS+=intltool".  Remove now unused
intltool/buildlink3.mk
