#267 Update to usage in list of help command line switches

[Allan Cunliffe]

Xena Testing Branch (changeset date 29/06/2010 12:29)

The command line help for Xena does not make it clear that you need to enter parameters for file, output directory and plugins directory.

Typing java -jar xena.jar --help at a command prompt, I get:

usage: xena
-f,--file <arg> Input files
-h,--help Print usage information
-o,--outputDirectory <arg> Output directory
-p,--pluginsDirectory <arg> Path to plugins directory

Can this be updated to show the user that three arguments (file, output directory and plugins directory) are required to normalise files.

For example:

usage: xena [--file <arg>] [--outputDirectory <arg>] [--pluginsDirectory <arg>]

Also, the long form of an argument is not standard as '=' is not used (e.g. --file <arg> vs. --file=<arg>)

[Justin Waddell]

The plugins directory should not be mandatory (it can just default to the "plugins" directory under the current working directory).

[Matthew Oliver]

Updated the usage to correctly identify which parameters are required and if the plugins directory is not supplied then the console attempts to find one in the local directory.

Tested in Xena testing branch (rfe-3026203)

A couple of things:

* The plugins option can't be stated on it own. If it is, the help contents is displayed.
* The switch for file option should be "file" not "files"

Can you please adjust the arguments statement to be:
usage: xena [--outputDirectory <arg> --file <args> [--pluginsDirectory <arg>]]
