# Text Trix Builder

HELP="
Builds and packages the Text-Trix-modified Ostermiller Syntax Highlighter.

Syntax:
	build.sh [ --java java-compiler-binaries-path ] [ --plug ]
	[ --pkg ] [ --help ]
(\"sh \" might need to precede the command on the same line, in case
the file build.sh does not have executable permissions.)

Parameters:
	--clean: Cleans all .class files and exits.
	
	--jar: Builds a jar file.
	
	--java=java//binaries/path: Specifies the path to javac, 
	jar, and other Java tools necessary for compilation.  
	Alternatively, the JAVA variable can be hand-edited 
	to specify the path, which would override any command-line 
	specification.
	
	--help: Lends a hand by displaying yours truly.
