(description

"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.c `pkg-config
|
|
--libs --cflags glib-2.0` for instance, rather than hard-coding values
|
|
on where to find glib (or other libraries). It is language-agnostic, so
|
|
it can be used for defining the location of documentation tools, for
|

instance.")))
