Module updates for MARC error checking

I have posted new versions of MARC::Errorchecks (to CPAN and my home 
page [1]), MARC::Lint::CodeData (included in Errorchecks, my home 
page, and most recent version will be available in CVS on 
SourceForge, as part of MARC::Lint), and MARC::Lintadditions (at my 
home page only, since I would eventually like to move these checks 
into MARC::Lint). I have also posted a new version of 
LCSHchangesparserpl110.txt (to the inprocess directory of my home 
page). The script is used to parse a text version of LC's weekly new 
and changed headings Web pages to leave a tab-delimited text file of 
headings that have changed. Following LC's recent website redesign, 
the script currently complains about the first lines of the input 
files, but it seems to do a reasonably good job of creating the list 
of changed headings.

A question: Both MARC::Lint and MARC::Errorchecks in CPAN include a 
copy of MARC::Lint::CodeData. Should I update MARC::Lint to version 
1.43 with the only change being the inclusion of the new version 1.14 
of CodeData?

I have posted a new module, MARC::Lint::Lint_Authority.pm. This will 
be a module essentially copying MARC::Lint, but with a data section 
and methods for validating MARC format for Authority data rather than 
Bibliographic. An initial version of this module appears in the 
inprocess directory. I have not done much testing, but what little I 
have done seems to successfully do basic lint validation.

A description of the changes for the modules and the script appears below.
