Here is a description from the author iamalinuxfreak:

this is a flasher that i mentioned last night, little did u know that it was already halfway done. this flasher is nice because theres no clutter, theres just the functions to flash and thats it. it depends on you to check the battery, you supply the customized files, like gameboots and it will flash it over for you, theres plenty of functions. there is always a chance of bricking, but its been tested thouroughly, and works fast and smooth and the menus are simple. good for people starting out. i might release the source code later. thanks to unique warrior for releasing his source, if i didnt have it to study i wouldnt know how to flash. enjoy, and READ THE README!
