| 10 # --------------------------- |
| 11 # |
| 12 # Configure a subdirectory. This is an alternative to |
| 13 # AC_CONFIG_SUBDIRS that allows pointing the source directory |
| 14 # somewhere else. The build directory is always a subdirectory of the |
| 15 # top build directory. This is heavilly based on Autoconf 2.64's |
| 16 # _AC_OUTPUT_SUBDIRS. |
| 17 # |
| 18 # Inputs: |
| 19 # - SRC-DIR-NAME is the source directory, relative to $srcdir. |
| 20 # - BUILD-DIR-NAME is `top-build -> build' |
