jAstyle is based on Artistic Style 1.23
Usage : java -jar jastyle.jar [options] Source1.java Source2.java [...]
java -jar jastyle.jar [options] < Original > Beautified
When indenting a specific file, the resulting indented file RETAINS the
original file-name. The original pre-indented file is renamed, with a
suffix of ".orig" added to the original filename.
Wildcards (* and ?) may be used in the filename.
A 'recursive' option can process directories recursively.
By default, astyle is set up to indent C/C++/C#/Java files, with 4 spaces
per indent, a maximal indentation of 40 spaces inside continuous statements, and NO formatting.
Long options (starting with '--') must be written one at a time.
Short options (starting with '-') may be appended together.
Thus, -bps4 is the same as -b -p -s4.

Artistic Style looks for a default options file in the
following order:
1. The contents of the ARTISTIC_STYLE_OPTIONS environment
variable if it exists.
If a default options file is found, the options in this file will be parsed BEFORE the command-line options.
Long options within the default option file may be written without
the preliminary '--'.
