+The options used used usually look like:
+  %configure \
+    --prefix=/usr \
+    --sysconfdir=/etc \
+    --bindir=/usr/bin \

+    --with-selinux

 
 

-The installation directories are controlled by $prefix, $exec_prefix
-$sysconfdir and $libdir-name. Documentation, development files are
-installed below $prefix, binaries are installed below $exec_prefix,
-libraries below $exec_prefix/$libdir-name.
+The options used in a RPM spec file look like:
