-# 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_LATEX_BIBTEX_TEST(FILEDATA,BIBDATA,VARIABLETOSET,[NOCLEAN])
-#
-# DESCRIPTION
-#
-#   This macros creates a bib file called contest.bib with BIBDATA,
-#   executes the latex application with FILEDATA as input, then runs
-#   bibtex on the resulting aux file, and finally sets VARIABLETOSET
-#   to yes or no depending on the result. If NOCLEAN is set, the folder
-#   used for the test is not deleted after testing.
-#
-#   The macro assumes that the variables PDFLATEX and BIBTEX are set.
-#
-#   Adapted from the macro AX_LATEX_TEST by Sébastien Villemot.
