+The RTEMS Source Builder is a stand alone tool based on another tool called the
+*SpecBuilder* written by Chris Johns. The *SpecBuilder* was written around 2010
+for the RTEMS project to provide Chris with a way to build tools on hosts that
+did not support RPMs. At the time the RTEMS tools maintainer only supported
+*spec* files and these files held all the vital configuration data needed to
+create suitable tool sets. The available SRPM and *spec* files by themselves
+where of little use because a suitable ``rpm`` tool was needed to use them. At
+the time the available versions of ``rpm`` for a number of non-RPM hosts were
+broken and randomly maintained. The solution Chris settled on was to use the
+*spec* files and to write a Python based tool that parsed the *spec* file
+format creating a shell script that could be run to build the package. The
+approach proved successful and Chris was able to track the RPM version of the
+RTEMS tools on a non-RPM host for a number of years.
+
+The *SpecBuilder* tool did not build tools or packages unrelated to the RTEMS
+Project where no suitable *spec* file was available so another tool was
+needed. Rather than start again Chris decided to take the parsing code for the
+*spec* file format and build a new tool called the RTEMS Source Builder.
