# The package name specified on the pkg-config command line is defined to
# be the name of the metadata file, minus the .pc extension. If a library
# can install multiple versions simultaneously, it must give each version
# its own name (for example, GTK 1.2 might have the package name "gtk+"
# while GTK 2.0 has "gtk+-2.0").
