# libcurl for uClinux and Asterisk, 
# Keith Huang Feb 2008
# SSL supported added by Nick Basil Sep 2008
# 
# usage: make -f libcurl.mk libcurl-package 
#
# Run after building uClinux-dist, copies shared libs to
# uClinux-dist/staging, ready for use in Asterisk if 
# required.
#
# Requires libssl (make -f libssl.mk libssl) which transfers 
# libcrypto and libssl to the staging area.
