+dnl find_apr.m4 : locate the APR include files and libraries
+dnl
+dnl This macro file can be used by applications to find and use the APR
+dnl library. It provides a standardized mechanism for using APR. It supports
+dnl embedding APR into the application source, or locating an installed
+dnl copy of APR.
+dnl
+dnl APR_FIND_APR([srcdir [, builddir, implicit-install-check]])
+dnl
+dnl where srcdir is the location of the bundled APR source directory, or
+dnl empty if source is not bundled.
+dnl
+dnl where blddir is the location where the bundled APR will will be built,
+dnl or empty if the build will occur in the srcdir.
+dnl
+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 apr_found : "yes", "no", "reconfig"
+dnl
+dnl apr_config : If the apr-config tool exists, this refers to it. If
+dnl apr_found is "reconfig", then the bundled directory
+dnl should be reconfigured *before* using apr_config.
+dnl
+dnl Note: this macro file assumes that apr-config has been installed; it
+dnl is normally considered a required part of an APR installation.
+dnl
+dnl If a bundled source directory is available and needs to be (re)configured,
+dnl then apr_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 apr_found is "yes" or "reconfig", then the caller should use the
+dnl value of apr_config to fetch any necessary build/link information.
