executing shell commands (like cp)

Hi

How do I execute a copy (cp) of some files once they are generated by 
automake. The situation is I have a automake/autoconf/libtool generated 
library that is loadable by python. libtool generates this library and 
places it in <project-name>/.libs/lib<name>.so.0.0.0. What I want to do 
is copy the file lib<name>.so.0.0.0 into a directory of my choosing 
after the build process of it is completed. Any suggestions?

Thanks very much...
