+#   python fig2pstex.py ${base}.fig ${base}.pstex
+# This command generates
+#   ${base}.eps    the converted eps file
+#   ${base}.pstex  a tex file that can be included in your latex document
+#       using '\input{${output}}'.
+#
+# Note:
+#   Do not use this command as
+#     python fig2pstex.py file.fig file.eps
+#   the real eps file will be overwritten by a tex file named file.eps.
