>You should notice the backquote character which is used
in this command line. A common mistake when you start a GTK+
based development is to use quotes instead of backquotes. If
you do so, the compiler will complain about an unknown file
called <TT
CLASS="FILENAME"
>pkg-config gtk+-2.0 --cflags --libs</TT
>. The
text in backquotes is an instruction to your shell to
substitute the output of executing this command into the
commandline.</P
