* FML interpreter. Europagate, 1995
*
* $Log: fmltest.c,v $
- * Revision 1.1 1995/02/06 13:48:09 adam
- * Initial revision
+ * Revision 1.4 1995/02/09 16:06:08 adam
+ * FML can be called from the outside multiple times by the functions:
+ * fml_exec_call and fml_exec_call_str.
+ * An interactive parameter (-i) to fmltest starts a shell-like
+ * interface to FML by using the fml_exec_call_str function.
+ *
+ * Revision 1.3 1995/02/09 13:07:15 adam
+ * Nodes are freed now. Many bugs fixed.
+ *
+ * Revision 1.2 1995/02/07 16:09:24 adam
+ * The \ character is no longer INCLUDED when terminating a token.
+ * Major changes in tokenization routines. Bug fixes in expressions
+ * with lists (fml_sub0).
+ *
+ * Revision 1.1.1.1 1995/02/06 13:48:10 adam
+ * First version of the FML interpreter. It's slow and memory isn't
+ * freed properly. In particular, the FML nodes aren't released yet.
