"""
Wrapper class to automatically handle copyright headers and header guards
for generated scripts. Meant to be invoked via `with` statement similar to
creating a file.
- `path`: The path of the file to be created. Can be passed a raw string, an
isolated SCons target, or a full SCons target list. If a target list contains
multiple entries, produces a warning & only creates the first entry.
- `guard`: Optional bool to determine if a header guard should be added. If
unassigned, header guards are determined by the file extension.
- `prefix`: Custom prefix to prepend to a header guard. Produces a warning if
provided a value when `guard` evaluates to `False`.
- `suffix`: Custom suffix to append to a header guard. Produces a warning if
provided a value when `guard` evaluates to `False`.
