[syslinux] lua assist

[Geert Stappers]

Hello,

For Lua inclusion in Syslinux an idea to ship with an com32/lua/assist
directory and an com32/lua/patches directory.

In the patches directory patches against a pristine lua tarball
and the assist dir contains scripts for further tayloring.

This is what I have in mind:
| milleune at inertia:~
| $ git clone http://www.stappers.it/tracking/syslinux/.git syslinux-lua-stappers
| milleune at inertia:~
| $ cd syslinux-lua-stappers/
| milleune at inertia:~/syslinux-lua-stappers
| $ cd com32/lua
| milleune at inertia:~/syslinux-lua-stappers/com32/lua
| $ ls
| assist  patches  README.syslinux
| milleune at inertia:~/syslinux-lua-stappers/com32/lua
| $ cat README.syslinux 
| 
| The Syslinux bootloader family has support for Lua.
| 
| However default build and default released tarballs don't have
| Lua included, but programms in the assist directory help you
| with getting Lua for Syslinux.
| 
| Typing
| 
|    assist/get
| 
| will get you the Lua source from Internet.
| 
| 
| With
| 
|   assist/patch
| 
| are patches applied.
| 
| 
| Use
| 
|   assist/modimf
| 
| to modify a makefile in the Syslinux tree,
| so that Lua gets build for Syslinux.

It is work from august and misses recent work on the Lua patches.

How to 'git checkout the_lua_branch' ?
