Focal-81 is originally written by Dave Conroy <mrm@Sceard.COM>.
Modified and debugged by Akira KIDA <SDI00379@niftyserve.or.jp>

List of modifications:

  - Now compile under ANSI-C environment.
    Still compile under K&R C, but require ANSI compatible headers.

  - Supports 'lib list' command using <dirent.h> directory handling
    libraries.  i.e. opendir(), readdir(), ... etc.  I think they are
    POSIX compatible.

  - Also supports 'lib list' command on MS-DOS / MS-C environment.

  - Uses simple hash mechanisms for symbol tables.

  - Critical bug in releasing nested 'for' control stack frame is
    now fixed.


I (Kida) tested in the following environments:

  Sun SPARCstation running SunOS 4.1.3 + sun cc (K&R)
  Sun SPARCstation running SunOS 4.1.3 + gcc 2.6.3 (ANSI)
  Sun SPARCstation running Solaris 2.3 + SunPro cc 2.0.1 (ANSI)
  Sun SPARCstation running Solaris 2.3 + gcc 2.6.3 (ANSI)
  HP9000 model 720 (HPPA) running HPUX 8.05 + hp cc (ANSI)
  HP9000 model 720 (HPPA) running HPUX 8.05 + gcc 2.5.8 (ANSI)
  MS-DOS + MS-C 6.0 (ANSI)
  MS-DOS + LSI C-86 3.30 (very close to ANSI)


Copyright or lack of it:

Akira KIDA puts all the modifications in the public domain.
Although I'm not sure what the original copyright condition is.
