-DESCRIPTION="jam"
+SUMMARY="Build tool, replacement for make"
+DESCRIPTION="
+	Jam is a small open-source build tool that can be used as a replacement 
+	for Make. Even though Jam is a lot simpler to use than Make, it is far 
+	more powerful and easy to master. Its design is sufficiently clear to 
+	allow any average programmer to extend it with advanced features at will.
+
+	The main differences between Jam and Make are as follows:
+
+	- Jam uses ‘Jamfiles’ instead of ‘Makefiles’.
+
+	- Jamfiles do not normally contain toolset-specific rules or actions. 
+	  They are thus portable among distinct compilers.
+
+	- Jamfiles are a lot simpler than Makefiles to write and understand, 
+	  while providing the same functionality, and much, much more.
