# SYNOPSIS
#
# AX_CHECK_OPENSSL([action-if-found[, action-if-not-found]])
#
# DESCRIPTION
#
# Look for OpenSSL in a number of default spots, or in a user-selected
# spot (via --with-openssl). Sets
#
# OPENSSL_INCLUDES to the include directives required
# OPENSSL_LIBS to the -l directives required
# OPENSSL_LDFLAGS to the -L or -R flags required
#
# and calls ACTION-IF-FOUND or ACTION-IF-NOT-FOUND appropriately
#
# This macro sets OPENSSL_INCLUDES such that source files should use the
# openssl/ directory in include directives:
#
# #include <openssl/hmac.h>
