/**
 * A mapping from class name to property name to property type.
 *
 * # Format
 *
 * This structure is of the form
 * [ class_name => [ property_name => type ] ]
 *
 * # How to Generate
 *
 * ```sh
 * svn checkout https://svn.php.net/repository/phpdoc/en/trunk phpdoc;
 *
 * cd phpdoc;
 *
 * find . -type f -path '*.xml -exec cat {} \; \
 *   | tr "\n" " " \
 *   | grep -o "<type>[^<]*<\/type>\s*<varname linkend=\"[^\.]*\.props.[^\"]*\"" \
 *   | while read l; do T=`echo $l | cut -d ">" -f2 | cut -d "<" -f1`; N=`echo $l | cut -d "\"" -f2 | cut -d "." -f1,3`; printf "$T $N\n"; done \
 *   | tee types
 * ```
 *
 * and then pipe that through
 *
 * ```perl
 * #!/usr/bin/perl
 * my %classes = {};
 * while(<>) {
 *     chomp;
 *     if (/^([^ ]*) ([^\.]*)\.(.*)$/) {
 *         my $type = $1;
 *         my $class = $2;
 *         my $property = $3;
 *         push(@{ $classes{$class} }, "'$property' => '$type'");
 *     } else {
 *         print STDERR "FAIL\n";
 *     }
 * }
 * while (($class, $details) = each %classes) {
 *     print "    '$class' => [\n        ";
 *     print join(",\n        ", @{ $details });
 *     print "\n    ],\n";
