CPAN::WAIT adds some comands to the CPAN
shell() to perform searches on a WAIT server. It connects to a WAIT server using a simple protocoll resembling NNTP as described in RFC977. It uses the WAIT::Client module to handle this connection. This in turn inherits from Net::NNTP from the libnet package. So you need Net::NNTP to use this module.
If no direct connection to the WAIT server is possible, the modules tries to connect via your HTTP proxy (as given by the CPAN configuration). Be warned though that the emulation of the stateful protocol via HTTP is slow.
CPAN::WAIT::TIMEOUT specifies the number of seconds to wait for an answer from the server. The default is 20. You may want to set it to some larger value if you have a slow connection.
The commands available are:
Displays a short help message if called without arguments. If you provide the name of another command you will get more information on this command if available. Currently only wq will be explained.
Limit the number of hits returned in a search to count. The limit usually is set ot 10 of you don't set it.
Send a query to the server.
Here are some query examples:
information retrieval free text query information or retrieval same as above des=information retrieval `information' must be in the description des=(information retrieval) one of them in description des=(information or retrieval) same as above des=(information and retrieval) both of them in description des=(information not retrieval) `information' in description and `retrieval' not in description des=(information system*) wild-card search au=ilia author names may be misspelled
You can build arbitary boolean combination of the above examples. Field names may be abbreviated. For further information see http://ls6-www.informatik.uni-dortmund.de/CPAN
The result should look like this:
wq au=wall 1 8.039 a2p - Awk to Perl translator 2 8.039 s2p - Sed to Perl translator 3 8.039 perlipc - Perl interprocess communication (signals, fifos, pipes, safe subprocesses, sockets, and semaphores) 4 8.039 ExtUtils::DynaGlue - Methods for generating Perl extension files 5 8.039 h2xs - convert .h C header files to Perl extensions 6 8.039 Sys::Syslog, openlog, closelog, setlogmask, syslog - Perl interface to the UNIX syslog(3) calls 7 8.039 h2ph - convert .h C header files to .ph Perl header files 8 8.039 Shell - run shell commands transparently within perl 9 8.039 pl2pm - Rough tool to translate Perl4 .pl files to Perl5 .pm modules. 10 8.039 perlpod - plain old documentation

Fetches the full text from the server and runs perlpod on it. Make sure that you have perlpod in your path. Also check if your perlpod version can handle absolute pathes. Some older versions ironically do not find a document if the full patch is given on the command line.
