+Compile certain portion
+
+       See ./configure --help and use --disable-* and --enable-* options.
+
+        It's also possible to disable all the programs and enable only wanted.
+        For example:
+       
+       ./configure --disable-all-programs --enable-fallocate
+
+       Note that the configure script tracks dependencies between libs and
+        tools. Always see warning messages and follow error messages if any
+        dependence is necessary. For example to compile mount(8) you need also
+        libmount, libblkid and libuuid:
+
+       ./configure --disable-all-programs --enable-mount --enable-libmount \
+                    --enable-libblkid --enable-libuuid
