10 # This script allows NetSurf and its libraries to be built without
11 # requiring installation into a system.
12 #
13 # Usage: source env.sh
14 #
15 # Controlling variables
16 # HOST sets the target architecture for library builds
17 # BUILD sets the building machines architecture
18 # TARGET_WORKSPACE is the workspace directory to keep the sandboxes
19 #
20 # The use of HOST and BUILD here is directly comprable to the GCC
21 # usage as described at:
22 # http://gcc.gnu.org/onlinedocs/gccint/Configure-Terms.html
