5 | # SYNOPSIS | |

7 | # AC_DEFINE_DIR(VARNAME, DIR [, DESCRIPTION]) | |
8 | # | |
9 | # DESCRIPTION | |
10 | # | |
11 | # This macro sets VARNAME to the expansion of the DIR variable, taking | |
12 | # care of fixing up ${prefix} and such. | |
13 | # | |
14 | # VARNAME is then offered as both an output variable and a C preprocessor | |
15 | # symbol. | |
16 | # | |
17 | # Example: | |
18 | # | |
19 | # AC_DEFINE_DIR([DATADIR], [datadir], [Where data are placed to.]) | |
