5# OBSOLETE MACRO

7# Deprecated because it does not comply with the GNU Coding Standards. See
8# the autoconf manual section "Defining Directories" for alternatives.

10# SYNOPSIS
11#
12# AX_DEFINE_DIR(VARNAME, DIR [, DESCRIPTION])
13#
14# DESCRIPTION
15#
16# This macro sets VARNAME to the expansion of the DIR variable, taking
17# care of fixing up ${prefix} and such.
18#
19# VARNAME is then offered as both an output variable and a C preprocessor
20# symbol.
21#
22# Example:
23#
24# AX_DEFINE_DIR([DATADIR], [datadir], [Where data are placed to.])
