+#                       [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.
