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.])
