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