andrey@robot9000 /tmp $ grep graphite /usr/portage/profiles/use*.desc |
| 45 |
/usr/portage/profiles/use.local.desc:app-office/libreoffice:graphite - |
| 46 |
Enable support for non-Roman fonts via media-gfx/graphite2 |
| 47 |
/usr/portage/profiles/use.local.desc:app-portage/eix:strong-optimization |
| 48 |
- Adds several more agressive CXXFLAGS/LDFLAGS for optimization like |
| 49 |
graphite (if available). May cause trouble with some buggy compiler |
| 50 |
versions. Absense of this USE flag does not strip user's *FLAGS |
| 51 |
/usr/portage/profiles/use.local.desc:media-libs/harfbuzz:graphite - |
| 52 |
Enable support for non-Roman fonts via media-gfx/graphite2 |
| 53 |
/usr/portage/profiles/use.local.desc:media-libs/silgraphite:pango - |
| 54 |
Enables the pango-graphite pango module. |
| 55 |
/usr/portage/profiles/use.local.desc:sys-devel/gcc:graphite - Add |
| 56 |
support for the framework for loop optimizations based on a polyhedral |
| 57 |
intermediate representation |
