NAME

Search::Equidistance - Perl extension for blah blah blah

SYNOPSIS

  use Search::Equidistance;
  decode ($search_string, $MAXSKIP, $file);

ABSTRACT

  This should be the abstract for Search::Equidistance.
  The abstract is used when making PPD (Perl Package Description) files.
  If you don't want an ABSTRACT you should also edit Makefile.PL to
  remove the ABSTRACT_FROM option.

DESCRIPTION

  First converts file to contiguous_single_line text composed of
  alphabets and digits only. Then for skip 1(normal text) thru MAXSKIP,
  generates partial texts, searches the string (case-insensitive, forward,
  and reverse) and lists the find as follows. 

  Example output:

  $ run_decode.pl ABC 5 code.10000
  [Skip=3]
  <0:3334>CBA(405)ABC(811)
  <1:3333>CBA(1249)
  [Skip=4]
  <2:2500>CBA(900)
  [Skip=5]
  <0:2000>CBA(1115)
  <4:2000>ABC(406)CBA(1827)

  "=== String ABC are found 7 times (forward & reverse) ==="

  where
  [Skip=3] has 3 partial texts (text-0, text-1, text-2)
  <0:3334> means text-0 (of length 3334),
           code.10000 being length 10000
  CBA(405)ABC(811) => string CBA found in position 405, and
                      ABC in position 811 (starting position 0)
  

EXPORT

None by default.
