# INSTALLATION NOTES
#
# Requires the ruby-zoom package (which requires YAZ) and the marc gem.
#
# ruby-zoom: http://ruby-zoom.rubyforge.org/
# See the installation instructions there
#
# marc gem: http://rubyforge.org/projects/marc/
# $ sudo gem install marc
#
# NOTE ruby-zoom installs its own marc.rb file that will conflict with
# marc! You will need to delete ruby-zoom's marc.rb or rename it 
# for the marc gem to work.
# 
# On my system it was installed in
#   /usr/local/lib/ruby/site_ruby/1.8/marc.rb
# but you'll have to look for it wherever your system put it.

# USAGE
#
# isbn2marc [-q] [-d marcfile] [-x xmlfile] ISBN
#
# -q          Run quietly, don't list servers queried and don't 
# --quiet     dump MARC to STDOUT
#             By default isbn2marc tells STDERR what it's doing
#
# -d marcfile Dump MARC record to file
# --dump
#
# -x xmlfile  Dump MARCXML record to file
# --dumpxml
#
# -w apikey   Query WorldCat using API key
# --worldcat
#
# -l level    WorldCat service level (default or full)
# --worldcatlevel Default is default

# EXAMPLES
#
# Find a MARC record for the first volume of Casanova's HISTORY OF
# MY LIFE and pretty print it:
#
# $ isbn2marc 0801856620 
#
# Find a MARC record for Terry Pratchett's THIEF OF TIME and write
# a binary MARC file to disk as well as pretty printing it:
#
# $ isbn2marc -d thief.marc 0552148407
#
# Find a MARC record for the first omnibus volume of the University of
# Chicago Press's edition of Anthony Powell's A DANCE TO THE MUSIC OF TIME,
# but don't show the record on the screen:
#
# $ isbn2marc -q -d stringham.marc -x templer.xml 0226677141
#
# Find MARC records for all ISBNs in a file and save them on disk:
#
# $ cat isbns.txt
# 0439064864
# 0439064872
# 0439136350
# 0439136369
# 0439139600
# 059035342X
# 0736646736
# $ isbn2marc -f isbns.txt -d harry-potter.marc
#
# Try WorldCat first, which will speed things up, and get a full record:
#
# $isbn2marc --worldcat yourAPIkeyhere --worldcatlevel full 1551922460
#
# Find a MARC record but don't display it or save it:
#
# $ isbn2marc -q 0195024028
#
# You'd be a bit silly to run that often.

# TO DO
#
# Proper ISBN validity check.
