Syncronizing External Sources
-----------------------------

Some source files are pristinely copied from several Xorg repositories
and they must be syncronized with each Xorg release to get new features.

The following list details the syncronization procedure of every foreign
resource. Additionally, the version the resource was last syncronized to
is located next to the file name. 

   * xproto-7.0.18 (keysymdef.h): copied from source tree.

       $ git clone git://anongit.freedesktop.org/git/xorg/proto/x11proto
       $ cd x11proto
       $ git checkout [latest-tag]
       $ cp keysymdef.h $TARGET/keysymdef.h

   * libX11-1.3.99.901 (ks_tables.h): generated by build process.

       $ git clone git://anongit.freedesktop.org/xorg/util/macros
       $ git clone git://anongit.freedesktop.org/xorg/lib/libX11
       $ cd macros
       $ ./autogen.sh && ./configure && make
       $ cd ../libX11
       $ ACLOCAL="aclocal -I ../macros" ./autogen.sh && ./configure
       $ make -C src ks_tables.h
       $ cp src/ks_tables.h $TARGET/ks_tables.h

Other sources must be modified before the driver can use them. Thus, the
update procedure cannot be fully automated.

    * libX11-1.3.99.901 (symname.c): based on src/StrKeysym.c
      (kstoucs.c): based on src/xlibi18n/imKStoUCS.c
