Hi there,
When I install a new package I run `emerge -pv foo` to look at the USEs
it supports. In the past I have looked these up just by grepping, e.g.:
$ grep foo /usr/portage/profiles/use.*
/usr/portage/profiles/use.desc:foomaticdb - Adds support for the
foomatic printing driver database
$
However I have recently learned to use `euse -i foo` instead. This is
much more convienient than grepping because one can use the Bash
history: up-arrow, ctrl-w to delete the last word & type in or paste the
name of the next USE to check it. However this is clumsy when you have a
package (like mplayer) with many USE flags.
What I would like to be able to do is:
$ $magicusecommand category/package
doc - Install HTML wxWidgets docs and wxpython API reference.
examples - Install interactive demo module browser and sample applets.
samba - Adds support for SAMBA (Windows File and Printer sharing)
$
The command should print out the descriptions for ALL the USE flags
supported by the category/package, but only for that category/package.
Ideally it should show if they're currently enabled or not.
I can't be the only person to desire this feature - surely there must be
a package or command do do this. I can't find this in `man portage` as
an advanced version of `emerge -pv package`. Can anyone tell me what
$magicusecommand is called, please?
