SWick - A player in the Stallman Team

The changes in this release are:
 
- The utilities will now ask interactively for a password if it was
  not provided with the -s command line option.  This avoids security
  problems related to shell history files.
 
- Support for octal and hexadecimal numbers has been added.  They can
  be used in both the records and selection expressions.
 
- It is now possible to select a given number of random records in
  many of the utilities using the -m command line option.
 
- The -n option now accepts a list of indexes, supporting ranges.
 
- The new -U (uniq) option for recsel removes duplicated fields in the
  output records.
 
- The new -q (quick) option allows to quickly search for the desired
  record without having to provide a complete selection expression.
 
- Auto generated fields are now considered integers by default.  This
  avoids repetitive patterns in record descriptors involving %auto and
  %type.
 
- Tab characters are now allowed in blank lines betwwen records.
 
- The API in rec.h is now better documented with comments, and
  improved.
 
- recfix now exits with an error status if there is a parse error in
  some input file.
 
- The usage of the internal data structures has been _vastly_
  improved, resulting in a much faster operation.
 
- Internal cleanup and code factorization.
 
- Many, many, many bug fixes :D
