Overview

:startdoc::manifest copies files

Copies a list of files to the specified directory. The files will be copied using the relative filepath from Dir.pwd, or the file basename if the filepath is not relative to Dir.pwd. For example: when copying to ‘/target_dir’ from Dir.pwd = ‘/dir’:

source path              target path
/dir/path/to/file.txt    /target_dir/path/to/file.txt
/path/to/file.txt        /target_dir/file.txt

Existing files are backed up as ‘<file>before<timestamp>’ into the standard backup directory. Up-to-date files are not copied. Raises an error for non-existing and non-file input files, as well as a non-directory target_dir.
