+dnl find_apu.m4 : locate the APR-util (APU) include files and libraries
+dnl
+dnl This macro file can be used by applications to find and use the APU
+dnl library. It provides a standardized mechanism for using APU. It supports
+dnl embedding APU into the application source, or locating an installed
+dnl copy of APU.
+dnl
+dnl APR_FIND_APU([srcdir, path, implicit-install-check])
+dnl
+dnl where srcdir is the location of the bundled APU source directory, or
+dnl empty if source is not bundled.
+dnl where path is the prefix to the location where the bundled APU will
+dnl will be built.
+dnl where implicit-install-check set to 1 indicates if there is no
+dnl --with-apr option specified, we will look for installed copies.
+dnl
+dnl Sets the following variables on exit:
+dnl
+dnl apu_found : "yes", "no", "reconfig"
+dnl
+dnl apu_config : If the apu-config tool exists, this refers to it. If
+dnl apu_found is "reconfig", then the bundled directory
+dnl should be reconfigured *before* using apu_config.
+dnl
+dnl Note: At this time, we cannot find *both* a source dir and a build dir.
+dnl If both are available, the build directory should be passed to
+dnl the --with-apr-util switch.
+dnl
+dnl Note: the installation layout is presumed to follow the standard
+dnl PREFIX/lib and PREFIX/include pattern. If the APU config file
+dnl is available (and can be found), then non-standard layouts are
+dnl possible, since it will be described in the config file.
+dnl
+dnl If a bundled source directory is available and needs to be (re)configured,
+dnl then apu_found is set to "reconfig". The caller should reconfigure the
+dnl (passed-in) source directory, placing the result in the build directory,
+dnl as appropriate.
+dnl
+dnl If apu_found is "yes" or "reconfig", then the caller should use the
+dnl value of apu_config to fetch any necessary build/link information.
