# @BLURB: common ebuild functions for autotools-based packages |
| 10 |
# @DESCRIPTION: |
| 11 |
# autotools-utils.eclass is autotools.eclass(5) and base.eclass(5) wrapper |
| 12 |
# providing all inherited features along with econf arguments as Bash array, |
| 13 |
# out of source build with overridable build dir location, static archives |
| 14 |
# handling, libtool files removal. |
| 15 |
# |
| 16 |
# Please note note that autotools-utils does not support mixing of its phase |
| 17 |
# functions with regular econf/emake calls. If necessary, please call |
| 18 |
# autotools-utils_src_compile instead of the latter. |
| 19 |
