=head1 NAME
rmadison -- Remotely query the Debian archive database about packages
=head1 SYNOPSIS
=over
=item B<rmadison> [I<OPTIONS>] I<PACKAGE> ...
=back
=head1 DESCRIPTION
B<dak ls> queries the Debian archive database ("projectb") and
displays which package version is registered per architecture/component/suite.
The CGI at B<https://qa.debian.org/madison.php> provides that service without
requiring SSH access to ftp-master.debian.org or the mirror on
mirror.ftp-master.debian.org. This script, B<rmadison>, is a command line
frontend to this CGI.
=head1 OPTIONS
=over
=item B<-a>, B<--architecture=>I<ARCH>
only show info for ARCH(s)
=item B<-b>, B<--binary-type=>I<TYPE>
only show info for binary TYPE
=item B<-c>, B<--component=>I<COMPONENT>
only show info for COMPONENT(s)
=item B<-g>, B<--greaterorequal>
show buildd 'dep-wait pkg >= {highest version}' info
=item B<-G>, B<--greaterthan>
show buildd 'dep-wait pkg >> {highest version}' info
=item B<-h>, B<--help>
show this help and exit
=item B<-s>, B<--suite=>I<SUITE>
only show info for this suite
=item B<-r>, B<--regex>
treat PACKAGE as a regex
B<Note:> Since B<-r> can easily DoS the database ("-r ."), this option is not
supported by the CGI on qa.debian.org and most other installations.
=item B<-S>, B<--source-and-binary>
show info for the binary children of source pkgs
=item B<-t>, B<--time>
show projectb snapshot and reload time (not supported by all archives)
=item B<-u>, B<--url=>I<URL>[B<,>I<URL> ...]
use I<URL> for the query. Supported shorthands are
B<debian> https://api.ftp-master.debian.org/madison
B<new> https://api.ftp-master.debian.org/madison?s=new
B<qa> https://qa.debian.org/madison.php
B<ubuntu> https://ubuntu-archive-team.ubuntu.com/madison.cgi
B<udd> https://qa.debian.org/cgi-bin/madison.cgi
B<all> https://qa.debian.org/cgi-bin/madison.cgi?table=all
B<archive> https://qa.debian.org/cgi-bin/madison.cgi?table=archived
B<ports> https://qa.debian.org/cgi-bin/madison.cgi?table=ports
See the B<RMADISON_URL_MAP_> variable below for a method to add
new shorthands.
=item B<--version>
show version and exit
=item B<--no-conf>, B<--noconf>
don't read the devscripts configuration files
=back
ARCH, COMPONENT and SUITE can be comma (or space) separated lists, e.g.
--architecture=amd64,i386
=head1 CONFIGURATION VARIABLES
The two configuration files F</etc/devscripts.conf> and
F<~/.devscripts> are sourced by a shell in that order to set
configuration variables. Command line options can be used to override
configuration file settings. Environment variable settings are
ignored for this purpose. The currently recognised variables are:
=over 4
=item B<RMADISON_URL_MAP_>I<SHORTHAND>=I<URL>
Add an entry to the set of shorthand URLs listed above. I<SHORTHAND> should
be replaced with the shorthand form to be used to refer to I<URL>.
Multiple shorthand entries may be specified by using multiple
B<RMADISON_URL_MAP_*> variables.
=item B<RMADISON_DEFAULT_URL>=I<URL>
Set the default URL to use unless overridden by a command line option.
For Debian this defaults to debian. For Ubuntu this defaults to ubuntu.
=item B<RMADISON_ARCHITECTURE>=I<ARCH>
Set the default architecture to use unless overridden by a command line option.
To run an unrestricted query when B<RMADISON_ARCHITECTURE> is set, use
B<--architecture='*'>.
=item B<RMADISON_SSL_CA_FILE>=I<FILE>
Use the specified CA file instead of the default CA bundle for curl/wget,
passed as --cacert to curl, and as --ca-certificate to wget.
=item B<RMADISON_SSL_CA_PATH>=I<PATH>
Use the specified CA directory instead of the default CA bundle for curl/wget,
passed as --capath to curl, and as --ca-directory to wget.
=back
=head1 NOTES
B<dak ls> was formerly called B<madison>.
The protocol used by rmadison is fairly simple, the CGI accepts query the
parameters a, b, c, g, G, r, s, S, t, and package. The parameter text is passed to
enable plain-text output.
