**

0.38 Fri May  3 14:47:09 CEST 2002
 - Removed a (silly) debug message.
 - Fool-proof for ascii input.
 - Numeric input works with LB::IP::input() (just as ascii input).
 - Numeric input asks for input until it gets a valid input.

0.37 Wed Apr 24 08:54:00 CEST 2002
 - New mechanism of libraries loading: loading instances of extension instead
   of a plain module.
 - doc/library.pod modified to reflect this.

0.36 Mon Apr 22 20:44:10 CEST 2002
 - jqbf98 now understands the -v flag (verbose)
 - New examples tpr00.bf, palin.bf
 - IP.pm now has two methods spush_vec and spop_vec. Befunge.pm modified to
   take advantage of those methods.
 - IP.pm now has a method spush_args to push (and convert) arguments on the stack.
 - IP.pm comes with a storage facility to allow library to fetch and store
   whatever data they want. This is highly experimental and the interface may
   change in future releases.

0.35 Tue Apr 16 17:20:29 CEST 2002
 - LaheySpace::labels_lookup() now also returns the velocity that found the label.
 - Minor pod update.

0.34 Tue Apr 16 15:00:27 CEST 2002
 - Minor bug fix in LaheySpace.pm. I discovered it by chance, since it's
   a tiny little bug that did not seem to break anything.
 - LaheySpace now has a labels_lookup() method, that allow to search for
   labels inside comments. This will be used in Inline::Befunge and maybe
   some extensions will use this non-standard mechanism.
 - Minor update to doc/library.pod

0.33 Mon Apr 15 17:21:23 CEST 2002
 - Fancy stuff added in order to support Inline::Befunge (does not change
   the default behavior)
 - One more debug message

0.32 Mon Apr 15 12:01:53 CEST 2002
 - POD fixing in doc/library.pod

0.31 Mon Apr 15 09:41:21 CEST 2002
 - Smarter way of handling parameters.
 - jqbf98 interpreter now handles parameters.

0.30 Sun Apr 14 15:53:19 CEST 2002
 - Befunge.pm now has an Object Oriented interface.
 - rewriting tests to take the new interface into account.

**

0.20 Sat Apr 13 13:08:17 CEST 2002
 - Befunge.pm modified to understand libraries semantics:
   parens (to load/unload) and capital letters.
 - IP modified in order to accept the libraries semantics.
 - New directory lib/ where to put libraries.
 - New libraries FOO and HELO
 - New test 22lib -> test libraries semantics.
