+Changes between release 2.5.0 (xxDec93) and release 2.4.5:
+
+       - Snapshot for installation on ell.
+
+       - Self-contained scanners (modulo yywrap()).
+
+       - Three new routines are available for manipulating stacks
+         of start conditions: yy_push_state( int new_state ),
+         void yy_pop_state(), and int yy_top_state().
+
+       - Flex now generates #line directives relating the code it
+         produces to the output file; this means that error messages
+         in the flex-generated code should be correctly pinpointed.
+
+       - A new "-ooutput" option writes the generated scanner to "output".
+         If used with -t, the scanner is still written to stdout, but
+         its internal #line directives use "output".
