This file contains additional configuration written by modules in the NetBeans IDE.
5+
The configuration is intended to be shared among all the users of project and
6+
therefore it is assumed to be part of version control checkout.
7+
Without this configuration present, some functionality in the IDE may be limited or fail altogether.

<!--
11+
Properties that influence various parts of the IDE, especially code formatting and the like.
12+
You can copy and paste the single properties, into the pom.xml file and the IDE will pick them up.
13+
That way multiple projects can share the same settings (useful for formatting rules for example).
14+
Any value defined here will override the pom.xml file value but is only applicable to the current project.
