Creating XML Spec Files

RPM spec files are text files containing structured information. It is a natural progression to write RPM spec files using XML. The tool rpmxmlbuild will build an RPM package from an XML-formatted spec file.
For example, Listing 10-1 holds a spec file in XML format.
Listing 10-1: An XML spec file.

Bash is the Bourne-Again SHell, which is a widely used command interpreter
on Unix systems. Bash is a program that reads from standard input, the
keyboard. A user types something and the program will evaluate what he has
typed and do something with it, like running a program.</description>

Note
XML spec files are a very experimental feature. Future releases of RPM will likely provide more support for XML spec files. The format will likely change.
