The original puzzle has 9 triangles per face (size = 3) and
has period 3 turning (i.e. the face or points turn in 120 degree
intervals). The puzzle was designed by Uwe Meffert and called
the Pyraminx. This has 2^5*3^8*6!/2 or 75,582,720 different
combinations.
Another puzzle Senior Pyraminx 3x3x3 exists only on paper, it
has period 2 turning (i.e. edges turn with 180 degree intervals)
but the corners would fall off unless it had some tricky
mechanism. (This may be the same as the Master Pyraminx which
has 446,965,972,992,000 different combinations).
Another puzzle (which was not widely distributed), the Junior
Pyraminx (and similarly the Junior Pyraminx Star, a octahedron
formed by two tetrahedra, this has 7!*3^6 or 3,674,160 different
combinations), has 4 triangles (size = 2) per face and at the
time I designed this computer puzzle thought that it had only
period 2 turning (i.e the edges rotate). It turns out the puzzle
has a period 4 turning (edges turn with 90 degree intervals)
which makes it analogous to the 2x2x2 Rubik's cube. This puzzle
makes various non-tetrahedral shapes. The puzzle contained here
has no period 4 turning flexability.
Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

Add USES=xorg USES=gl, ports categories g
Add USES=xorg and USES=gl to ports in categories starting with 'g'.
While here, try to sprinkle other USES (mostly gnome and sdl) as needed.
MASTER_SITES cleanup.
- Replace ${MASTER_SITE_FOO} with FOO.
- Merge MASTER_SITE_SUBDIR into MASTER_SITES when possible. (This means 99.9%
of the time.)
- Remove occurrences of MASTER_SITE_LOCAL when no subdirectory was present and
no hint of what it should be was present.
- Fix some logic.
- And generally, make things more simple and easy to understand.
While there, add magic values to the FESTIVAL, GENTOO, GIMP, GNUPG, QT and
SAMBA macros.
Also, replace some EXTRACT_SUFX occurences with USES=tar:*.

Convert most of remaining ports that depend on xorg-libraries to
modular xorg.
- supply corresponding USE_XORG for all imake-using ports that need it
- USE_IMAKE no longer implies USE_XLIB in absence of USE_XORG
- retire USE_X_PREFIX which is not really used anywhere after the
above change
- a few minor nits like whitespace and SF macro
