.IX Header "OVERVIEW"
Checkstyle is a development tool to help programmers write Java code that
adheres to a coding standard. It automates the process of checking Java code
to spare humans of this boring (but important) task. This makes it ideal for
projects that want to enforce a coding standard.
.PP
Checkstyle is highly configurable and can be made to support almost any coding
standard.
.PP
Checkstyle is highly configurable and can be made to support almost any coding
standard. Example configuration files are supplied supporting the Sun Code
Conventions and Google Java Style.
