exclude_path:
description:
- Remote absolute path, glob, or list of paths or globs for the file or files to exclude from I(path) list and glob expansion.
- Use I(exclusion_patterns) to instead exclude files or subdirectories below any of the paths from the I(path) list.

description:
- Glob style patterns to exclude files or directories from the resulting archive.
- This differs from I(exclude_path) which applies only to the source paths from I(path).

description:
- Allows you to force the module to treat this as an archive even if only a single file is specified.
