+# URIPARSER_CHECK ([DEFAULT-ACTION], [MINIMUM-VERSION],
+#                       [ACTION-IF-YES], [ACTION-IF-NO])
+# Checks for uriparser library.  DEFAULT-ACTION is the string yes or no to
+# specify whether to default to --with-uriparser or --without-liburiparser.
+# If not supplied, DEFAULT-ACTION is yes.  MINIMUM-VERSION is the
+# minimum version of uriparser to accept.  Pass the version as a regular
+# version number like 0.8.5. If not supplied, any version is
+# accepted.  ACTION-IF-YES is a list of shell commands to run if
+# uriparser was successfully found and passed the various tests.
+# ACTION-IF-NO is a list of shell commands that are run otherwise.
+# Note that using --without-uriparser does run ACTION-IF-NO.
+#
+# This macro #defines HAVE_URIPARSER if a working uriparser setup is
+# found, and sets @URIPARSER@ and @URIPARSER_CPPFLAGS@ to the necessary
+# values.
+#
+# Users may override the detected values by doing something like:
+# URIPARSER="-luriparser" URIPARSER_CPPFLAGS="-I/usr/myinclude" ./configure
