# Gone:         the variable $line is gone (using $_ now)
#
# 1998/12/11
# Added:        catdoc test (is catdoc runnable?)    <carl@dpiwe.tas.gov.au>
# Changed:      push line semi-colomn wrong.         <carl@dpiwe.tas.gov.au>
# Changed:      matching works for end of lines now  <carl@dpiwe.tas.gov.au>
# Added:        option to rigorously delete all punctuation <carl@dpiwe.tas.gov.au>
#
# 1999/02/09
# Added:        option to delete all hyphens         <grdetil@scrc.umanitoba.ca>

# 1999/02/15
# Added:        check for some file formats          <Frank.Richter@hrz.tu-chemnitz.de>
# 1999/02/25
# Added:        uses pdftotext to handle PDF files   <grdetil@scrc.umanitoba.ca>
# Changed:      generates a head record with punct.  <grdetil@scrc.umanitoba.ca>
# 1999/03/01
# Added:        extra checks for file "wrappers"     <grdetil@scrc.umanitoba.ca>
#               & check for MS Word signature (no longer defaults to catdoc)
# 1999/03/05
# Changed:      rejoin hyphenated words across lines <grdetil@scrc.umanitoba.ca>
#               (in PDFs) & remove multiple punct. chars. between words (all)

# Changed:      fix handling of minimum word length  <grdetil@scrc.umanitoba.ca>
#
# 1999/05/05
# Changed:	Adapted for Debian.		<jdassen@wi.leidenuniv.nl>
#               Fixed C-ism.
