script for database schema

I know this question has been asked and answered before but I still need some clarification.

Is there a product (either commerical or public) that will produce a script to recreate the database including tablespaces, etc?

The answers I have heard are:
1. run exp without data. However the file this produces is one VERY long line that does not lend itself to editing.

2. there is something available from your Oracle Users Group. I am on the board of the new Los Angeles Users Group and I know have any idea how to obtain any software or even what might be available. Can anyone point me in the right direction?

Any other software suggestins would be appreciated. There must be something out there.

Thanks
