EDIT:
For the script, see the most recent version at bottom of the thread.I have just finished it out, and it needs a bit [much] more testing. Seems to work, though.
Extension Profiler is a tool that modifies its own dep file to include/remove other extensions. This lets the user create individual 'profiles,' collections of extensions which load under a particular name.
Profiler
To set up:
- reboot base
- put all extensions into optional directory
- put profiler-0.3.tcz into tce directory
- run profiler -R
- run profiler -s [yournewprofile] to create a new profile
- run profiler -a [extension] to add extensions to the new profile
Extension profile is loaded on next boot. Supports:
"profiler" is the Extension Profiler multi-tool.
USAGE: profiler [abcdlnrst] [EXTENSION] [PROFILE]
-a add add EXTENSION to next boot profile
-b backup make a backup all profiles to /tmp/profiles.tar.gz
-c current output name & list content of current profile
-d delete remove PROFILE. If needed, set base as next boot.
-l list list existing profiles
-n next output name & list content next boot profile
-R reset create ~/.profiler-0.3 config directories and files
-r remove remove EXTENSION from next boot profile
-s set set PROFILE as active
-t tce list contents of tce/optional
At first, run with -R to set up.

EDIT: Now working on v0.4 - adding installer, moving config files to /home/tc/.config/ sudirectory, etc.
EDIT: Removed 0.3 files - 0.4 posted below.
