[Android Themes] intronauta:
In essence is the same idea and the structure is very simple and similar: /XTRAS for add extra files (equivalent to the raw folder) and /MORPH for morph themes, and both folders are equivalent to the root path "/", so you must build the full path in both folders. We changed the folder names thinking that would be easier to identify their funtions. You can check the README file for more info and get basic instructions.

Sorry but my english is very very bad and I've problems translating your post. I think that jrsoft is referring to add the possibility in the morphing process to inject into apks only files that previously exist and ignore if doesn't (only overwrite and exclude the new files). This feature was a user request to give the possibility to add differents files for the same resource in the mod, e.g in some roms the author change some strings (like the tipical notification panel background) respect to stock values. Then they could add the same resource with differents names and let to the script inject only by matching, adapting the mod to the different versions/apks without adding all files by default. In MOD.config this feature is named "clean_morphing". With the zip binary was impossible to do easily (we tried some tricks) because is date dependent and only update if the mod file is newer than the included in the apk (apart of the UTC vs local time limitation in kernel). Thanks god we found a 7z compiled for android. Then if you need it, you can do it, but by default this feature is disabled and all files will be added into apk without mercy :P

Beside this, in the MOD.config file you can:

Set a mod_name. This is the modname/version/author and will be added after the existing ro.build.display.id or ro.modvesion string (if exists in build.prop) for identify that we've installed (visible in settings->about system), but you can leave it blank, of course.

Enable/disable backup

Enable/disable log file (usefull if you need some detailed info about the process)

Enable/disable log on screen (is more or less the same info added to the log file but showed on screen)

Set your sdcard folder name used in the recovery (e.g some recoveries set emmc like external sd instead sdcard and/or you can set a custom folder like /sdcard8 if you need it, but we must keep the generic "sdcard" in the XTRAS folder and let to the script to rename it with the appropriate name in function of this settings. Firstly the script will check if the internal sd is mounted, if doesn't, will be set the default external sd and adapt all generic sdcard paths).

Set a custom mount comand if you need it for mount the system and data partitions (e.g in sgs1 the generic CWM command "mount /data" doesn't works in all cases and depending if we're using lagfix or not we'll need the "full command" to mount it).

The process check for free space required in the sdcard necessary for the backup and, if the backup is enabled and the space isn't enough, exit with prompt. The same mounting the required partitions. The idea is that to guarantee the backup creation is a priority before start the process.

In general the process isn't as fast like villaintheme tool, especially if you have enabled the backup, because to build it checking all the modification made by MORPH and XTRAS is laborious, can't be done only copying and pasting files from the updater-script. The process requires copying everything to a temporal folder in RAM and work there. But anyway isn't alarming and is always recommended have a backup for whatever may happen...

Obviously if the theme is huge, compress the backup take some time. But the goal is that the backup is ready to be flashed and you can revert all modification made by the mod with their original permissions, including the changes made in build.prop about the mod_version if it was defined in MOD.config. Only reboot into recovery and flash it. This is the best safeguard (excluding nandroid backups, of course) specially when you have bootloops for incompatibilities between mod and rom or simply if you don't like the theme, mod, etc.. and want to return to the previous scenario like nothing had happened.

In outline, this is what is.
