K This is version 2.0 of Walker, a program to traverse a single site's Gopher  tree.  It is invoked with:  % $ walker host.domain port output-file   J where host.domain is the fully qualified domain name of the target system,K port is the Gopher port number (defaults to 70) and output-file is the name 6 of the output file generated (defaults to walker.out).  C The 'host.domain' name must be the name that is emitted by a Gopher K directory listing; if the host part of a Gopher directory selector does not K match this name, Walker will assume that the directory is for a remote link 2 and will not try to obtain the directory contents.  K Walker will look for a configuration file on the target system (walker.ctl, B veronica.ctl or robots.txt) and will refrain from traversing thoseB directories that are disallowed.  See walker.ctl for the format of
 this file.  G The files walker.c, robots.c, *.opt, walker.mms and make_walker.com are H required to build walker.exe; "@build xxx" will build walker for the xxxK TCP/IP package.  Currently Walker will compile and run under DECC/Multinet, K DECC/UCX (and probably any TCP/IP package the emulates UCX), VAXC/Multinet, I and OSF/1.  It hasn't been tested, but should run on VAXC/UCX and generic - Unix systems that support a socket interface.   G glance.c is a program that takes the Walker output file and generates a  "Gopher tree at a glance".  K walker_index.com will invoke build_index and generate a searchable database  of all the gopher titles found.   
