| michael@0 | 9 | # and usr/share/pkgconfig (relative to the sysroot) and that they output paths |
| michael@0 | 10 | # relative to some parent path of the sysroot. |
| michael@0 | 11 | # This assumption is valid for a range of sysroots, in particular: a |
| michael@0 | 12 | # LSB-compliant root filesystem mounted at the sysroot, and a board build |
| michael@0 | 13 | # directory of a Chromium OS chroot. |
