* Removing /usr/share/doc
* checking 292 files for package collisions
* This package will overwrite one or more files that may belong to other
* packages (see list below). You can use a command such as `portageq
* owners / <filename>` to identify the installed package that owns a
* file. If portageq reports that only one package owns a file then do
* NOT file a bug report. A bug report is only useful if it identifies at
* least two or more packages that are known to install the same file(s).
* If a collision occurs and you can not explain where the file came from
* then you should simply ignore the collision since there is not enough
* information to determine if a real problem exists. Please do NOT file
* a bug report at https://bugs.gentoo.org/ unless you report exactly
* which two packages install the same file(s). See
* https://wiki.gentoo.org/wiki/Knowledge_Base:Blockers for tips on how
* to solve the problem. And once again, please do NOT file a bug report
* unless you have completely understood the above message.
