+      Jam is a program construction tool, like make(1).
+
+      Jam recursively builds target files from source files, using dependency
+      information and updating actions expressed in the Jambase file, which is
+      written in jam's own interpreted language. The default Jambase is compiled
+      into jam and provides a boilerplate for common use, relying on a
+      user-provide file "Jamfile" to enumerate actual targets and sources.
