\`configure' configures XBPS to adapt to many kinds of systems.

By default, \`make install' will install all the files in
\`/usr/local/sbin', \`/usr/local/lib' etc.  You can specify
an installation prefix other than \`/usr/local' using \`--prefix',
for instance \`--prefix=\$HOME'.

--prefix=DIR 		Install architecture-independent files in PREFIX
--exec-prefix=DIR 	Install architecture-dependent files in EPREFIX
--sbindir=DIR 		System admin executables [PREFIX/sbin]
--libdir=DIR 		Object code libraries [PREFIX/lib]
--includedir=DIR 	C header files [EPREFIX/include]
--mandir=DIR 		Man documentation [EPREFIX/share/man]
--datadir=DIR 		Read-only architecture-independent data [EPREFIX/share]
--etcdir=DIR 		Configuration files [PREFIX/etc]
--pkgconfigdir=DIR 	pkg-config directory [EPREFIX/lib/pkgconfig]
--testsdir=DIR		Test suite directory [EPREFIX/tests]

--verbose 		Disable silent build to see compilation details
--enable-api-docs 	Install XBPS API Library documentation (default disabled)
--enable-debug		Build with debugging code and symbols (default disabled)
--enable-static 	Build XBPS static utils (default disabled)
--enable-tests		Build and install Kyua tests (default disabled)
			Needs atf >= 0.15 (http://code.google.com/p/kyua)
