IP Packages are going to be created using HDL files in the repo. These files
need to be moved into the package directory for use in the package. This change
ensure that the files are made available. Its not the best as it copies ALL
files into the package directory and not just the needed files.
Script will copy source code, 3rd party IP and Xilinx project directory
into a scratch directory which it also creates. Script can be invoked
using the following option.
-c Copy Verilog source code and 3rd party IP to an already existing
syn/scratch/ directory. Perform no other functions.
-h Print this help info.
-l Symbolically link project files into the scratch dir instead of
copying them. Any changes to these file during building will thus be
propagated back into the repo.
-L Symbolically link project directory into the scratch instead of
copying it. This takes precedents over the '-l'.
