<!--
 This build file is used to create the lexer's Java source code.
 Whenever you change bash.flex you have to run this build script.

 We're using the patched jflex library provided by JetBrains.

 Please notice that you COULDN'T use JFlex Ant Task for building
 lexer as long as it doesn't support additional arguments parameter
 ("charat" argument is required in order to build lexers
 for IntelliJ IDEA plugins)
