4 This class enables translation of Dojo resource bundles using gettext format.
6 Requires polib from http://polib.googlecode.com
8 Source event definitions are structured as follows:
10 MSG_ID1: "This is a message with 1 variable - ${0}.",
11 MSG_ID2: "This is a message with two variables: ${0} and ${1}."
14 Note that this is a deliberately limited subset of the variable substitution
15 allowed by http://api.dojotoolkit.org/jsdoc/dojo/1.2/dojo.string.substitute

40 This class provides methods for extracting translatable strings from
