=head1 NAME
PPM - Perl Package Manager: locate, install, upgrade software packages.
=head1 SYNOPSIS
ppm genconfig
ppm help [command]
ppm info [package1 .. packageN]
ppm install [--location=location] package1 [... packageN]
ppm query [--case|nocase] [--searchtag=abstract|author|title] PATTERN
ppm remove package1 [... packageN]
ppm search [--case|nocase] [--location=location] [--searchtag=abstract|author|title] PATTERN
ppm set [option]
ppm summary [--location=location] package1 [... packageN]
ppm verify [--location=location] [--upgrade] [package1 ... packageN]
ppm version
ppm [--location=location]
=head1 DESCRIPTION
ppm is a utility intended to simplify the tasks of locating, installing,
upgrading and removing software packages. It is a front-end to the
functionality provided in PPM.pm. It can determine if the most recent
version of a software package is installed on a system, and can install
or upgrade that package from a local or remote host.
ppm runs in one of two modes: an interactive shell from which commands
may be entered; and command-line mode, in which one specific action is
performed per invocation of the program.
ppm uses files containing an extended form of the Open Software
Description (OSD) specification for information about software packages.
These description files, which are written in Extensible Markup
Language (XML) code, are referred to as 'PPD' files. Information about
OSD can be found at the W3C web site (at the time of this writing,
http://www.w3.org/TR/NOTE-OSD.html). The extensions to OSD used by ppm
are documented in PPM.ppd.
=head1 COMMAND-LINE MODE
=over 4
=item Installing
ppm install [--location=location] package1 [... packageN]
Reads information from the PPD file (See the 'Files' section
below) for the named software package and performs an
installation. The 'package' arguments may be either package
names ('foo'), or pathnames (P:\PACKAGES\FOO.PPD) or URLs
(HTTP://www.ActiveState.com/packages/foo.ppd) to specific PPD files.
In the case where a package name is specified, and the '--location'
option is not used, the function will refer to repository locations stored
in the PPM data file (see 'Files' section below) to locate the PPD file
for the requested package.
=item Removing
ppm remove package1 [... packageN]
Reads information from the PPD file for the named software package and
removes the package from the system.
=item Verifying
ppm verify [--location=location] [--upgrade] [package1 ... packageN]
Reads a PPD file for the specified package and compares the currently
installed version of the package to the version available according to
the PPD. The PPD file is expected to be on a local directory or remote
site specified either in the PPM data file or on the command
line using the '--location' option. The --location' argument may be
a directory location or an Internet address. The '--upgrade' option
forces an upgrade if the installed package is not up-to-date.
If no packages are specified, all packages currently installed on the
system will be verified (and updated if desired). The PPD file for each
package will initially be searched for at the location specified with the
'--location' argument, and if not found will then be searched for using
the location specified in the PPM data file.
=item Querying
ppm query [--case|nocase] PATTERN
Reports currently installed packages matching 'PATTERN' or all installed
packages if no 'PATTERN' is specified.
ppm query [--case|nocase] [--searchtag=abstract|author|title] PATTERN
Searches for 'PATTERN' (a regular expression) in the ,
or tags of all installed packages, according to the value of
the '--searchtag' option. If a '--searchtag' value of 'abstract',
'author' or 'title' is not provided, any occurence of 'PATTERN' in the
package name will match successfully. A case-sensitive search will be
conducted by default, but this may be overridden by the options set in
the PPM data file, which may in turn be overridden by the '--nocase' or
'--case' option. If a search is successful, the name of the package
and the matching string are displayed.
ppm info [packages]
Prints a summary (name, version and abstract) of the specified installed
package, or all installed packages if no package is specified.
=item Searching
ppm search [--case|nocase] [--location=location] PATTERN
Displays a list of all packages matching 'PATTERN', with package
description (PPD) files available at the specified location. 'location'
may be either a remote address or a directory path. If a location is
not specified, the repository location as specified in the PPM data file
will be used.
ppm search [--case|nocase] [--location=location] [--searchtag=abstract|author|title] PATTERN
Searches for 'PATTERN' (a regular expression) in the <ABSTRACT>, <AUTHOR>
or <TITLE> tags of all PPD files at 'location', according to the value
of the '--searchtag' option. If a '--searchtag' value of 'abstract',
'author' or 'title' is not provided, any occurence of 'PATTERN' in
the package name will match successfully. 'location' may be either a
remote address or a directory path, and if it is not provided, repository
locations specified in the PPM data file will be used. A case-sensitive
search will be conducted by default, but this may be overridden by the
options set in the PPM data file, which may in turn be overridden by the
'--nocase' or '--case' option. If a search is successful, the name of
the package and the matching string are displayed.
=item Summarizing
ppm summary [--location=location] [package1 ... packageN]
Prints a summary (name, version and abstract) of the specified packages.
If no package is specified, a complete summary of all packages available
at a repository will be displayed (if available).
=item Error Recovery
ppm genconfig
This command will print a valid PPM config file (ppm.xml) to STDOUT. This
can be useful if the PPM config file ever gets damaged leaving PPM
unusable.
=back
=head1 INTERACTIVE MODE
If ppm is invoked with no command specified, it is started in interactive
mode. If the '--location' argument is specified, it is used as the
search location, otherwise the repositories specified in the PPM data file are
used. The available commands, which may be displayed at any time by entering
'help', are:
exit
- Exits the program.
