+  pkg-config is a helper tool used when compiling applications and libraries.
+  It helps you insert the correct compiler options on the command line so an
+  application can use gcc -o test test.cpkg-config --libs --cflags glib-2.0
+  for instance, rather than hard-coding values on where to find glib (or
+  other libraries).
