README for Sloandora system

This system requires UNIX, Linux, Mac OS X, or Cygwin with Perl and a
C compiler installed. If you can supply improvements to these
instructions, please contact me.

Create a directory, and put the following files into it:

  |sl.txt| is the Perl script, rename it |Sloandora|

  |concordiff.c.txt| is the C source, call it |concordiff.c|

Invoke an xterm, shell or Terminal window (or whatever it is called on
your system), log in, and @cd@ to the directory containing the two files.

Compile |concordiff.c| with the command:

  |gcc -o cdiff concordiff.c|

Make the @Perl@ script executable with the command:

  |chmod +x Sloandora|

Create four empty directories called |DBIS|, |dispatch|,
|parsed-DBIS|, and |topics|. (DBIS, an acronym for "DataBase of
Integer Sequences", was an old name for the [OEIS|oeis_homepage],)

Put the database files |eisBTfry00000.txt|, |eisBTfry00001.txt|, and
so on into the directory |DBIS|. (These files are no longer available
on the OEIS server, but with a friendly email to N.J.A. Sloane or
another site maintainer, you might be able to get them.)

Run the interactive script:

  |./Sloandora|

It will ask for a "topic". This is a name for an area of interest that
you would like to learn about.

It will then ask for the A-number of a sequence relevant to the topic.

It will then scan through the database looking for other possibly
relevant sequences, and display the A-number of its first
recommendation.

After that you will see the "command prompt"; at this point type
"help" to see a list of commands.
