# $NetBSD: tex.buildlink3.mk,v 1.14 2006/04/19 13:14:57 tonio Exp $
#
# A Makefile fragment for TeX and LaTeX packages
#
# 	* Determine the version of teTeX to be used.
#     Modify TEX_DEFAULT to change the default version (default to teTeX3)
#
#	* tex files are installed...
#	  	teTeX[2]
#	  		-> ${PREFIX}/share/texmf
#		teTeX3
#	  		-> ${PREFIX}/share/texmf-local
#   The variables PKG_TEXMFPREFIX and PKG_LOCALTEXMFPREFIX defines the main
#   texmf tree, where teTeX should install his own texmf tree, and the local
#   texmf tree, which is the place where other packages should install their
#   latex files, like additional styles.
#   NOTE: before all TeX-related packages are converted to use these
#   variables, we will keep
#   PKG_TEXMFPREFIX=PKG_LOCALTEXMFPREFIX=${PREFIX}/share/texmf
#
#	* Assume each package supports teTeX{2,3} by default.
#	  To change the supported TeX versions, define TEX_ACCEPTED
#	  explicitly before including mk/tex.buildlink3.mk.  Note that the
#	  order is important.
#
# * Optionally set TEX_DEPMETHOD to "build" to only add a build-time
#   dependency on TeX.  That may be useful for creating documentation
#
# Variables for users:
#
# TEX_DEFAULT
#   Description:
#     The user's favorite TeX implementation
#   Possible values:
#     teTeX2, teTeX3
#   Default value:
#     teTeX3
#
# Variables tex packages can provide:
#
# TEX_DEPMETHOD
#  Description:
#    Set tex as DEPENDS or BUILD_DEPENDS
#  Possible values:
#    run, build
#  Default value:
#    run
#
# TEX_ACCEPTED
#  Description:
#    Versions the package accepts (supports).
#  Possible values:
#    teTeX2, teTeX3
#  Default value:
#    teTeX2, teTeX3
#
# Variables provided for tex packages:
#
# PKG_TEXMFPREFIX
#   Description:
#     Path to the directory the standard tex files can be found
#   Possible values:
# 	  ${PREFIX}/share/texmf
# 	  ${PREFIX}/share/texmf-dist
#
# PKG_LOCALTEXMFPREFIX
#   Description:
#     Path to the directory the tex for extentions should be installed into
#   Possible values:
#   	${PREFIX}/share/texmf
#     ${PREFIX}/share/texmf-local
#
# TEX_TYPE
#   Description:
#     The type of the used TeX package
#   Possible values:
#     teTeX2, teTeX3
