New user and poster here,
This is a good feature, thank you for the script it worked well. :)
However I have an observation about the documentation, in the op post and the wiki there is reference to adding the flags as such
there is an example for the /etc/portage/make.conf but not /etc/portage/package.use.
In my case I added the recommended lines to both files.
This ends up creating a cryptic error message when you try to emerge something, the error below.
Invalid atom in /etc/portage/package.use: CPU_FLAGS_X86="avx
So I comment out the line added to the package.use and all is well.
The line added to both files from the script was the line below ( created from memory, funtoo is compiling away at the moment so not accessible)
CPU_FLAGS_X86="avx other ones here mmx mmxext sse sse2 sse3"
Should the docs exclude the info to add this line to package.use or give an example of use maybe?
