Object-orineted design re-implementation: simple field substitution and
lookups are working well.
Added some documentation about new features.

1 dpavlin 352 =head1 NAME
2    
3     Quick overview of things that are new in v2.x of WebPAC
4    
5     =head1 DESCRIPTION
6    
7     This document will describe new features in WebPAC version v2.x.
8     It will also attempt to document upgrade procedure to migrate
9     WebPAC v1.x installations to new v2.x.
10    
11     =head2 Input file handling
12    
13     Database files are now read in memory (using swap if not enough
14     memory is not available) and used from there.
15    
16     Also, in-memory structure will be dumped to temporary disk
17     cache, so that unchanged databases won't be re-read (and parsed) if source
18     database hasn't changed. Nice consequence of this is that memory lookups
19     are now for free (see below).
20    
21     =head2 Two-step processing of databases
22    
23     In first step database is read and in-memory structure is created (or
24     read from on-disk cache if source database hasn't changed).
25    
26     In second step output formats are created.
27    
28     =head2 Lookups
29    
30     For a start, lookup files are no longer supported. Since memory lookups
31     are newer and more powerfull (for example, each key can have more than
32     one value) it's not a great loss. However, you will have to re-write
33     your C<import_xml> files if you use lookup files to use memory lookups.
34    
35     Memory lookups (refered as lookups for new versions of WebPAC) are now
36     available always. Since whole database is availabe when creating
37     output linking should be much easier now.
