-# OBSOLETE MACRO
-#
-#   Deprecated because of licensing issues. The Lesser GPL imposes licensing
-#   restrictions on the generated configure script unless it is augmented
-#   with an Autoconf Exception clause.
-#
-# SYNOPSIS
-#
-#   AX_TEX_TEST(FILEDATA,VARIABLETOSET,[NOCLEAN])
-#
-# DESCRIPTION
-#
-#   This macros execute the pdftex application with FILEDATA as input and set
-#   VARIABLETOSET to yes or no depending on the result. If NOCLEAN is set,
-#   the folder used for the test is not delete after testing.
-#
-#   The macro assumes that the variable PDFTEX is set.
-#
-#   Adapted from the macro AX_LATEX_TEST by Sébastien Villemot.
