I need to be able to find which packages use a particular flag.
"gpac" to be specific:
Enable GPAC support when exporting to 3GPP format.
Any simple/global tools to find and list each and every
package available on Gentoo that has this flag as a option?
There is also an ebuild named "gpac"
Kino is one package the has this "gpac" flag.
How so I know it is the only one that requires
this gpac flag?
