  * FML interpreter. Europagate, 1995
  *
  * $Log: fmltest.c,v $
- * Revision 1.1  1995/02/06 13:48:09  adam
- * Initial revision
+ * Revision 1.5  1995/02/10 15:50:56  adam
+ * MARC interface implemented. Minor bugs fixed. fmltest can
+ * be used to format single MARC records. New function '\list'
+ * implemented.
+ *
+ * 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.
