Table Structure SQL or PLSQL

Question

In the spirit of the phrase ("... no need to re-invent the wheel"), does anyone have SQL or PLSQL coding already prepared [that they'd like to share] that will query the Oracle dictionary tables and return table name and structure info? I'm specifcally looking for coding that will return Owner, Table_name, Column_name, Column_order, an indication if the column is part of the PK, and Public_synonym for the table. I attempted searching past forum messages but received only computer-freeze. I'd like to do this with one "chunk" of code. Thank you kind sirs... (and/or ladies).

Something like this?
(I strongly suggest you run it per username, or you'll get a lot more data than you want ;-)
SELECT atc.owner
,atc.table_name
,syn.synonym_name public_synonym
,atc.column_name
,(SELECT 'Y'
FROM all_cons_columns acc
, all_constraints ac
WHERE acc.constraint_name = ac.constraint_name
AND acc.column_name = atc.column_name
and ac.owner = atc.owner
and atc.table_name = ac.table_name
and ac.constraint_type = 'P') "PK_ind"
FROM all_tab_cols atc
, all_synonyms syn
where atc.table_name = syn.table_name(+)
and atc.owner = syn.table_owner(+)
and syn.owner(+) = 'PUBLIC'
and atc.owner = UPPER('&owner')
order by atc.owner, atc.table_name, atc.column_id
