Changes for Net::Z3950 module, version 0.30

Changes between versions 0.29 and 0.30 (Fri Jul 19 13:55:45 2002):

Today's release is brought to you entirely by Dave Mitchell <davem@fdgroup.com> who has done an astonishing amount of really useful work on Net::Z3950. Thanks, Dave!

• Added the present() method and prefetch option to optimise multiple calls of record() in synchronous mode.
• Made $conn->close() actually clean up and close the connection.
• Fixed memory leak in receive.c, decodeAPDU()
• Added functions to decode Close request/response APDUs.
• Really do add ability to set custom exception-handler via die_handler option - I [Mike] did it wrong last time.
• Changed all print()s to die()s, which can be caught as exceptions.
• Commented out a debugging warn()
• Added a dummy test target to yazwrap/Makefile.PL to stop it complaining during make test [At last! - Mike]
• Removed debug => 5 from watcher creators.
• Updated the synchronous synopsis:
  • Replaced use of records() with record(), since the former is deprecated.
  • Added error-checking, so that people who cut-and-paste the synposis start off with good habits.
  • Added $conn->close(), so people know this doesn't happen automatically.
