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

41 This class provides methods for extracting translatable strings from
42 Evergreen's Dojo resource bundle files, generating translatable POT files,
43 reading translated PO files, and generating an updated Dojo resource bundle
44 files with additional or changed strings.
