-# LIBCURL_CHECK_CONFIG ([DEFAULT-ACTION], [MINIMUM-VERSION],
-#                       [ACTION-IF-YES], [ACTION-IF-NO])
-# ----------------------------------------------------------
-#      David Shaw <dshaw@jabberwocky.com>   May-09-2006
-#
-# Checks for libcurl.  DEFAULT-ACTION is the string yes or no to
-# specify whether to default to --with-libcurl or --without-libcurl.
-# If not supplied, DEFAULT-ACTION is yes.  MINIMUM-VERSION is the
-# minimum version of libcurl to accept.  Pass the version as a regular
-# version number like 7.10.1. If not supplied, any version is
-# accepted.  ACTION-IF-YES is a list of shell commands to run if
-# libcurl 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-libcurl does run ACTION-IF-NO.
-#
-# This macro #defines HAVE_LIBCURL if a working libcurl setup is
-# found, and sets @LIBCURL@ and @LIBCURL_CPPFLAGS@ to the necessary
-# values.  Other useful defines are LIBCURL_FEATURE_xxx where xxx are
-# the various features supported by libcurl, and LIBCURL_PROTOCOL_yyy
-# where yyy are the various protocols supported by libcurl.  Both xxx
-# and yyy are capitalized.  See the list of AH_TEMPLATEs at the top of
-# the macro for the complete list of possible defines.  Shell
-# variables $libcurl_feature_xxx and $libcurl_protocol_yyy are also
-# defined to 'yes' for those features and protocols that were found.
-# Note that xxx and yyy keep the same capitalization as in the
-# curl-config list (e.g. it's "HTTP" and not "http").
-#
-# Users may override the detected values by doing something like:
-# LIBCURL="-lcurl" LIBCURL_CPPFLAGS="-I/usr/myinclude" ./configure
-#
-# For the sake of sanity, this macro assumes that any libcurl that is
-# found is after version 7.7.2, the first version that included the
-# curl-config script.  Note that it is very important for people
-# packaging binary versions of libcurl to include this script!
-# Without curl-config, we can only guess what protocols are available,
-# or use curl_version_info to figure it out at runtime.
