| # SYNOPSIS |
| # |
| # AX_DEFINE_DIR(VARNAME, DIR [, DESCRIPTION]) |
| # |
| # DESCRIPTION |
| # |
| # This macro sets VARNAME to the expansion of the DIR variable, taking |
| # care of fixing up ${prefix} and such. |
| # |
| # VARNAME is then offered as both an output variable and a C preprocessor |
| # symbol. |
| # |
| # Example: |
| # |
| # AX_DEFINE_DIR([DATADIR], [datadir], [Where data are placed to.]) |
