Create a tex.buildlink3.mk file that is used by tex-using packages.

It includes the correct buildlink3.mk file from either
teTeX1 (print/teTeX1-bin), teTeX2 (print/teTeX-bin) or teTeX3
(print/teTeX3-bin). tex.buildlink3.mk will:

        * set PKG_TEXMFPREFIX to the base directory of the used texmf tree
	* set PKG_LOCALTEXMFPREFIX to the base directory of the local texmf
	  tree (for tex packages)
        * set LATEX_TYPE to the latex distribution used.

There are two variables that can be used to tweak the selection of
the latex implementation:

LATEX_DEFAULT is a user-settable variable whose value is the default
        latex distribution to use.

LATEX_ACCEPTED is a package-settable list of latex distributions
        that may be used by the package.

+# A Makefile fragment for tex and latex packages
+#
+# 	* Determine the version of teTeX to be used.
+#     Modify LATEX_DEFAULT to change the default version (default to teTeX2)
+#
+#	* tex files are installed...

+#   The variables PKG_TEXMFPREFIX and PKG_LOCALTEXMFPREFIX defines the main
+#   texmf tree, where teTeX should install his own texmf tree, and the local
+#   texmf tree, which is the place where other packages should install their
+#   latex files, like additional styles.
+#   NOTE: before all latex related packages are converted to use these
+#   variables, we will keep
+#   PKG_TEXMFPREFIX=PKG_LOCALTEXMFPREFIX=${PREFIX}/share/texmf
+#
+#	* Assume each package supports teTeX{2,3} by default.
+#	  To change the supported latex versions, define LATEX_ACCEPTED
+#	  explicitly before including mk/latex.buildlink3.mk.  Note that the order is
+#	  important.
+#
+# * Optionally set LATEX_DEPMETHOD to "build" to only add a build-time
+#   dependency on Latex. That may be useful for creating documentation
