# plutil.pl 1.6 - implementation of binary/UTF-8 (text) XML conversion of plist files
# does not (yet) support OS X plutil command line syntax
# 1.0 - first public release
# 1.1 - added support for date Type 3; fixed real Type 2
# 1.2 - fixed handling of empty arrays
# 1.3 - fixed handling of large strings and empty keys
# 1.4 - write utf8 in XML, convert as necessary on read
# 1.5 - read/write 8 byte integers and negative integers; handle special XML chars in dictionary keys
# - now requires Math::BigInt
# 1.6 - read/write data fields (type 4); also handles funny filenames better
# - now requires MIME::Base64
# 1.7 - correct binary to XML conversion
