| <title>HDEPEND</title> |
| <para> |
| The HDEPEND variable is used to represent build-time host dependencies. For |
| build-time target dependencies, use DEPEND (if the host is the target then both |
| HDEPEND and DEPEND will be installed on it). For EAPIs that support HDEPEND, |
| the emerge --root-deps option will have no effect, since it is not needed |
| when build-time dependencies are correctly specified with HDEPEND and DEPEND. |
| If ebuilds using EAPIs which <emphasis>do not</emphasis> support HDEPEND are |
| built in the same emerge run as those using EAPIs which <emphasis>do</emphasis> |
| support HDEPEND, the emerge --root-deps option will only apply to the former. |

| <title>Special "targetroot" USE flag</title> |
| <para> |
| The special "targetroot" USE flag will be automatically enabled for packages |
| that are built for installation into a target ROOT, and will otherwise be |
| automatically disabled. This flag may be used to control conditional |
| dependencies, and ebuilds that use this flag need to add it to IUSE unless it |
| happens to be included in the profile's IUSE_IMPLICIT variable. |
