Thanks for everyone who tested, reported bugs and shared their ideas
and wishes. Here is a list of people I would especially like to thank.

The original version of the pkgtools on which my work is heavily
based (exact version is pkgtools-10.1.0-i486-4):
  * Patrick J. Volkerding
  * others who have contributed into Slackware pkgtools

Shell script code not included in pkgtools-10.1.0-i486-4:
  * Jim Hawkins (faster code for View and Remove in 'pkgtool')
  * Jason Woodward (some code in 'makerepo' is from slapt-get's FAQ)
  * Michael G. Manry (some code in 'makerepo' was from swaret-tools)
  * Jeff Johnson (rpm2cpio as a sh script, used in functions.explode.sh)

Some utilities which are especially important for Tukaani pkgtools:
  * Igor Pavlov (LZMA compression)
  * Thomas E. Dickey (the 'dialog' program)

Major help with the pkgtools documentation and writing a better command
line interface for LZMA which is now part of LZMA utils used by pkgtools:
  * Ville Koskinen (IRC-nick: w-ber)

Testing, bug reports, ideas, feature requests, documentation proof
reading etc. (in alphabetical order, IRC nick in parenthesis):
