euse takes a parameter "-p" for per-package USE-flags which is working fine, but is not mentioned in the man page.
Is this an experimental feature or just forgotten?
-p switch was introduced Wed, 29 Dec 2010:

I can confirm that the "-p" option is not documented in the man page. It is however documented in the help text, which you can get by executing "euse --help".
There you can see that also other options are missing in the man page:
There is also inconsistency with the "--version" option - in the man page there is the lower case "-v", but in the help text there is upper case "-V". Nevertheless, both options are working :-).
And then there is wrong indentation in the man page for the last three options -a -h -v.
Tested with app-portage/gentoolkit-0.4.8
