Examples of com.gitblit.utils.cli.CmdLineParser

com.gitblit.utils.cli.CmdLineParser
Extended command line parser which handles --foo=value arguments.
The args4j package does not natively handle --foo=value and instead prefers to see --foo value on the command line. Many users are used to the GNU style --foo=value long option, so we convert from the GNU style format to the args4j style format prior to invoking args4j for parsing.
