+# OBSOLETE MACRO

+#   Deprecated because of licensing issues. The Lesser GPL imposes licensing
+#   restrictions on the generated configure script unless it is augmented

+#
+# SYNOPSIS
+#
+#   AX_TEX_TEST(FILEDATA,VARIABLETOSET,[NOCLEAN])
+#
+# DESCRIPTION
+#
+#   This macros execute the pdftex application with FILEDATA as input and set
+#   VARIABLETOSET the yes or no depending of 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.
