# This file is included by packages that need a TeX package to work.
#
# The following variables may be set by the pkgsrc user in mk.conf:
#
# TEX_DEFAULT
#	The user's favorite TeX implementation.
#
#	Possible values: teTeX3
#	Default value: teTeX3
#
# The following variables may be set by a package:
#
# TEX_DEPMETHOD
#	Select whether TeX is a runtime dependency or only needed
#	when building the package.
#
#	Possible values: build run
#	Default value: run
#
# TEX_ACCEPTED
#	List of TeX implementations that the package supports.
#
#	Possible values: teTeX3
#	Default value: teTeX3
#
# After including this file, the following variables may be used, but not
# in directives like .if, .for, etc.
#
# PKG_TEXMFPREFIX
#	Absolute pathname of the directory where the standard TeX files
#	can be found.
#
#	Typical values: ${PREFIX}/share/texmf ${PREFIX}/share/texmf-dist
#
# PKG_LOCALTEXMFPREFIX
#	Absolute pathname of the directory where extensions for TeX can
#	be found.
#
#	Typical values: ${PREFIX}/share/texmf ${PREFIX}/share/texmf-local
#
# TEX_TYPE
#	The TeX implementation that has been selected based on the
#	package's and the user's preferences.
#
#	Typical values: teTeX3
#

# NOTE: before all TeX-related packages are converted to use these
# variables, we will keep PKG_TEXMFPREFIX = PKG_LOCALTEXMFPREFIX =
# ${PREFIX}/share/texmf
