A virtual is a way for portage to have one of several option satisfy a |
| 34 |
dependency. It doesn't install anything but depends on one of a number of |
| 35 |
packages, in this case emacs and emacs-vcs. It means ebuild writers can |
| 36 |
depend on emacs but leave you the choice of which brand of emacs to use. |
| 37 |
|
| 38 |
Look at the ebuild, or look at the ebuild of virtual/editor to see what |
| 39 |
a mess ebuilds would be without virtuals. |
