M4 processor
Bravura Security Fabric uses an off-the-shelf text macro system called M4 to construct the skin files. If you want to perform any of the customizations described in this document you must use M4. An M4 macro processor is shipped with Bravura Security Fabric .
M4 is a tool used to expand short strings (macros) into longer strings. It was made popular on Unix systems as a way to manage sendmail configuration files more easily. For more information about M4, visit:
