PREAMBLE

 ZYDUX Project is a collection script to whose aim to cross build a small 
 GNU Linux operating system from scratch named ZYDUX.
 You can find official repository on https://github.com/rom1nux/zydux-forge


PREREQUIST
 
 Please install following package before using zydux-forge :
 $ apt-get install build-essential qemu


INSTALLATION

 Installation is simple as extract scripts and add directory to PATH

 1 - Extract zydux-forge.tar.bz2 where you want (ex: /usr/local/zydux-forge)    
     $ cd /usr/local
     $ tar xf zydux-forge.tar.bz2

 2 - Be sure scipts are executable
     $ chmod -R a+x /usr/local/zydux-forge

 3 - Add directory to PATH like
     $ export PATH=$PATH:/usr/local/zydux-forge
     (You can add this line to your .bashrc file to always add directory to PATH)


HOW TO USE

 When you install the zydux-forge, you will be able to start build

 1 - Create a working directory where you want for example in your home directory
     $ mkdir ~/workbench
     $ cd ~/workbench

 2 - You can execute every zydux-xxxx.sh function. The first time you execute command,
     a default configuration file "zydux-config.inc" is created in working directory.
     Adjust configuration in this file and execute the commands
     Launch zydux command without argument or with "help" argument to see the help


BUILD PROCEDURE

 Build is made in 2 main steps :
 - Build a cross compiler
 - Build the system with the cross compiler

 Here is a simple procedure :

 1 - Generate default configuration file
     $ zydux-forge.sh
     Adjust configuration as you need

 2 - Build the cross compiler (build in "toolchain" folder)
     $ zydux-toolchain.sh all

 3 - Build the system (build in "targer" folder)
     $ zydux-build.sh all

 4 - Create a hdd image (build in the working directory)
     $ zydux-image.sh build

 5 - Launch image in emulator
     $ zydux-image.sh qemu

In case of problem you can use "resume" command to resume the "all" command where tou were


ADJUSTING

If you want to manually adjust the system :

1 - Modify "target" directory as you need

2 - Rebuild the hdd image 
    $ zydux-image.sh build

3 - Launch image in emulator
    $ zydux-image.sh qemu

If you want to directly adjust the image

1 - Mount the image
    $ zydux-image.sh mount

2 - Modify the image mounter on "mnt" directory

3 - Unmount the image
    $ zydux-image.sh umount

4 - Launch image in emulator
    $ zydux-image.sh qemu
