Pooltype: Display WEB pool files
================================

  Pooltype shows the so-called "string number" of each string in a WEB
pool file (Note: WEB), as output by Tangle (Note: tangle
invocation), including the first 256 strings corresponding to the
possible input characters.  Pooltype primarily serves as an example of
WEB conventions to implementors of the TeX system.  Synopsis:

     pooltype [OPTION]... POOLFILE[.pool]

No path searching is done for POOLFILE.  Output is to standard output.

  The only options are `--help' and `--version' (Note: Common
options).

  As an example of the output, here is the (edited) output for
`tex.pool':
     0: "^^@"
     1: "^^A"
     ...
     255: "^^ff"
     256: "pool size"
     ...
     1314: "Using character substitution: "
     (23617 characters in all.)

  In Metafont and MetaPost, the first 256 characters are actually
represented as single bytes (i.e., themselves), not in the `^^'
notation.  Consider Pooltype as showing the results after conversion for
output.
