Changes for zSQLgate, version 0.03

23rd April 2002

Changes between versions 0.02 and 0.03 (Fri Mar 8 12:43:46 2002):

Added new config-file syntax
```
field "fieldName" = "columnName"
```
equivalent to the old (and now deprecated)
```
column "columnName" = "fieldName"
```
The new form is preferred since it is amenable to other, more complex RHSs enabling us to specify link-fields etc.
Add ability to search across multiple tables: this allows ``link fields'' to be resolved, as in fetching the name of book's author by following the book record's author_id record to a separate author record carrying the name.
Change XML record generation to be driven by the list of fieldnames, not that of columnnames.
Create new examples subdirectory.
Replace old music example with similar examples/books.
Move reading example to examples/csv.
Various tweaks to documentation.

Feedback to <mike@sql.z3950.org> is welcome!
