Tue Mar 9 12:17:05 2004 UTC (15 years, 9 months ago) by dpavlin
File MIME type: text/plain
File size: 26092 byte(s)
ported r248:252 from hidra branch:

r248: much improved installation instructions, especially for Debian
      GNU/Linux distributions
r249: changed use of Spreadsheet::ParseExcel and MARC to require/import so
      that dependency on those modules can be resolved in runtime.
r250: finished installation documentation
r251: removing dependency on HTML::Parser would ease installation
r252: smaller eval{} fiexes. eval{} logic should really move to
      parse_format.pm
