It also does not defines the variable `$CGIBASHOPTS_DIR` nor the function `cgibashopts_clean`, and do not use trap. **Note:** This is only available in versions 3 and above. Example of use : `. cgibashopts -n`

It defaults to `/tmp`. cgibashoptions will create in it a `cgibashopts-files.$$` subdirectory (where `$$` is the bash process number, unique per instance), shown in the `$CGIBASHOPTS_DIR` variable.
