Adam J. Stewart 73c978ddd9 install_tree, copy_tree can install into existing directory structures (#8289) ... Replace use of `shutil.copytree` with `copy_tree` and `install_tree` functions in `llnl.util.filesystem`. - `copy_tree` copies without setting permissions. It should be used to copy files around in the build directory. - `install_tree` copies files and sets permissions. It should be used to copy files into the installation directory. - `install` and `copy` are analogous single-file functions. - add more extensive tests for these functions - update packages to use these functions.		2018-08-15 09:30:09 -07:00
