A T-SQL script extracting DB schema info

Sometime I need to get a full view of a MS SQL database's schema details, e.g. user table and its columns, constraints, indexes, etc. And I prefer a plain text output instead of others (let's say XML). Since MS doesn't provide this and I can't find one from web, I wrote a script to implement this on my own:-

TSQL script

The output is tab spearated and can be easily imported into Excel/Access for a better look.

In write this I found TSQL in SQL 2000 is really depressing in constrast to PL/SQL. It event doesn't provide a convenient way of exporting output into an external file, as SPOOL command of PL/SQL does, unless COM is used. More terrible is the lack of support for parameterized cursor as well as 'inline' procedures or functions.

Does SQL 2005 provide any significant enhancements?
