VCard phone number normalizer

vcard-telnorm.cpp

/*! @brief Simple utility for normalizing phone numbers in VCard (.vcf) files
 *
 *  @author fluffy <[email protected]>
 *
 *  Requires the Google libphonenumber (C++ version), available at:
 *
 *  https://code.google.com/p/libphonenumber/
 *
 *  Just build this with -lphonenumber (or whatever equivalent is
 *  necessary on your toolchain of choice), and pipe the VCard on
 *  standard input and it comes out on standard output.  You can
 *  easily filter all the files in a directory with:
 *
 *  for i in *.vcf ; do
 *    echo $i ; fix-vcard < $i > $i.new && mv $i.new $i
 *  done 
 *
 *  Any warnings will be printed to stderr.
 *
 *  If you're using a CardDAV server, you can just access it with your
 *  standard WebDAV mounting tools, e.g.:
 *
 *  mkdir carddav
 *  mount.davfs https://cal.example.com/caldav.php/username carddav
 *  cd carddav/contacts
 *
 *  and then you can also use your text editor of choice to fix
 *  whatever flaws you find.
 *
 *  If you are in a locale other than US, pass it in as the command
 *  line arg.
