NAME

ufed - Gentoo Linux USE flags editor  

SYNOPSIS

ufed  

DESCRIPTION

UFED is a simple program designed to help you configure the systems USE flags (see below) to your liking. To select of unselect a flag highlight it and hit space.

UFED attempts to show you where a particular use setting came from. Each USE flag has a 3 character descriptor that represents the three ways a use flag can be set.

The 1st char is the setting from the /etc/make.profile/make.defaults file. These are the defaults for Gentoo as a whole. These should not be changed.

The 2nd char is the setting from the /etc/make.profile/use.defaults file. These will change as packages are added and removes from the system.

The 3rd char is the settings from the /etc/make.conf file. these are the only ones that should be changed by the user and these are the ones that UFED changes.

If the character is a + then that USE flag was set in that file, if it is a space then the flag was not mentioned in that file and if it is a - then that flag was unset in that file.

What are USE flags?

The USE settings system is a flexible way to enable or disable various features at package build-time on a global level and for individual packages. This allows an administrator control over how packages are built in regards to the optional features which can be compiled into those packages.

For instance, packages with optional GNOME support can have this support disabled at compile time by disabling the "gnome" USE setting. Enabling the "gnome" USE setting would enable GNOME support in these same packages.

The effect of USE settings on packages is dependent on whether both the software itself and the package ebuild supports the USE setting as an optional feature. If the software does not have support for an optional feature then the corresponding USE setting will obviously have no effect.

Also many package dependencies are not considered optional by the software and thus USE settings will have no effect on those mandatory dependencies.

A list of USE keywords used by a particular package can be found by checking the IUSE line in any ebuild file.

See http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2&chap=1 for more information on USE flags.

Please also note that if UFED describes a flag (Unknown) it generally means that it is either a spelling error in one of the 3 configuration files or it is not an officially sanctioned USE flag. Sanctioned USE flags can be found in /usr/portage/profiles/use.desc and in /usr/portage/profiles/use.local.desc.
