=head1 NAME
PPM - Perl Package Manager: locate, install, upgrade software packages.
=head1 SYNOPSIS
ppm genconfig
ppm help [command]
ppm install [--location=location] package1 [... packageN]
ppm query [--case|nocase] [--abstract|author] PATTERN
ppm remove package1 [... packageN]
ppm search [--case|nocase] [--location=location] [--abstract|author] PATTERN
ppm set [option]
ppm verify [--location=location] [--upgrade] [--force] [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 Using PPM
=over 4
=item 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 syntax of PPM commands is the same in interactive mode as it is in
command-line mode. The 'help' command lists the available commands.
ppm commands may be abbreviated to their shortest unique form.
=item Installing
ppm install [--location=location] package1 [... packageN]
Installs the specified software packages. Attempts to install from the
URL or directory 'location' if the '--location' option is specfied.
The 'package' arguments may be either package names ('foo'), 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, ppm will refer to the default repository locations.
See also: 'confirm' option.
=item Removing
ppm remove package1 [... packageN]
Reads information from the PPD file for the named software package and
removes the package from the system.
See also: 'confirm' option.
=item Verifying
ppm verify [--location=location] [--upgrade] [--force] [package1 ... packageN]
Verifies that the currently installed packages are up to date. If no
packages are specified as arguments, all installed packages will be verified.
If the '--upgrade' option is specified, any package for which an upgrade
is available will be upgraded.
If the '--location' option is specified, upgrades will be looked for at
the specified URL or directory.
If the '--force' option is specified, all currently installed packages will
be reinstalled regardless of whether they are out of date or not.
See also: 'confirm' option.
=item Querying
ppm query [--case|nocase] [--abstract|author] PATTERN
Searches for 'PATTERN' (a regular expression) in the name of any installed
package. If a search is successful, information about the matching
package(s) is displayed. If 'PATTERN' is omitted, information about
all installed packages will be displayed.
If either '--abstract' or '--author' is specified, PATTERN will be
searched for in the <ABSTRACT> or <AUTHOR> tags of the installed packages.
The '--case' and '--nocase' options can be used to override the default
case-sensitivity search settings.
See also: 'case' option.
=item Searching
ppm search [--case|nocase] [--location=location] [--abstract|author] PATTERN
Displays a list of any packages matching 'PATTERN' (a regular expression)
available from the specified location. If 'PATTERN' is omitted, information
about all available packages will be displayed.
If the '--location' option is specified, the specified URL or directory
will be searched. If '--location' is not specified, the repository location
as specified in the PPM data file will be searched.
If either '--abstract' or '--author' is specified, PATTERN will be
searched for in the <ABSTRACT> or <AUTHOR> tags of the available packages.
The '--case' and '--nocase' options can be used to override the default
case-sensitivity search settings.
See also: 'case' option.

The genconfig 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.
If required, this command should be run from a shell prompt:
C:\Perl\site\lib> ppm genconfig > ppm.xml
The getconfig command prints the location of the PPM configuration file
used at PPM startup.
=item Options
ppm set [option value]
Sets or displays current options. With no arguments, current option
settings are displayed.
Available options:
build DIRECTORY
- Changes the package build directory.
case [1|0]
- Sets case-sensitive searches. If one of '1' or '0' is
not specified, the current setting is toggled.
clean [1|0]
- Sets removal of temporary files from package's build
area, on successful installation of a package. If one of
'1' or '0' is not specified, the current setting is
toggled.
confirm [1|0]
- Sets confirmation of 'install', 'remove' and 'upgrade'.
If one of '1' or '0' is not specified, the current
setting is toggled.
downloadstatus NUMBER
- If non-zero, updates the download status after each NUMBER
of bytes transferred during an 'install'. This can be
reassuring when installing a large package (e.g. Tk) over
a low-speed connection.
force_install [1|0]
- Continue installing a package even if a dependency cannot
be installed.
more NUMBER
- Causes output to pause after NUMBER lines have been
displayed. Specifying '0' turns off this capability.
set repository --remove NAME
- Removes the repository 'NAME' from the list of repositories.
set repository NAME LOCATION
- Adds a repository to the list of PPD repositories for this
session. 'NAME' is the name by which this repository will
be referred; 'LOCATION' is a URL or directory name.
root DIRECTORY
- Changes the install root directory. Packages will be
installed under this new root.
save
- Saves the current options as default options for future
sessions.
trace
- Tracing level--default is 1, maximum is 4, 0 indicates
no tracing.
tracefile
- File to contain tracing information, default is 'PPM.LOG'.
verbose [1|0]
- Display additional package information for 'query' and
'search' commands.

baz [1.02 ] Interface to baz library
[install a package]
PPM> install foo
Install package foo? (y/N): y
[...]
[toggle confirmations]
PPM> set confirm
Commands will not be confirmed.
[see if 'baz' is up-to-date]
PPM> verify baz
An upgrade to package 'baz' is available.
[upgrade 'baz']
PPM> verify --upgrade baz
[...]
[forced upgrade of 'baz']
PPM> verify --upgrade --force baz
[...]
[toggle case-sensitive searches]
PPM> set case
Case-sensitive searches will be performed.
[display all available packages beginning with 'b']
PPM> search ^b
bar [2.91 ] supplies bar methods for perl5.
bax [0.072] module for manipulation of bax archives.
baz [1.03 ] Interface to baz library
[search for installed packages containing 'baz' in the ABSTRACT tag]
PPM> query --abstract baz
Matching packages found at P:\PACKAGES:
baz [1.03 ] Interface to baz library
PPM> quit
=item ppm install http://www.ActiveState.com/packages/foo.ppd
Installs the software package 'foo' based on the information in the PPD
obtained from the specified URL.
=item ppm verify --upgrade foo
Compares the currently installed version of the software package 'foo'
to the one available according to the PPD obtained from the location
specified for this package in the PPM data file, and upgrades
to a newer version if available.
=item ppm verify --location=P:\PACKAGES --upgrade foo
Compares the currently installed version of the software package 'foo'
to the one available according to the PPD obtained from the specified
directory, and upgrades to a newer version if available.
=item ppm verify --upgrade --force
Forces verification and reinstalls every installed package on the system,
using upgrade locations specified in the PPM data file.
=item ppm search --location=http://ppm.ActiveState.com/PPMpackages/5.6
Displays the packages with PPD files available at the specified location.
=item ppm search --location=P:\PACKAGES --author ActiveState
Searches the specified location for any package with an <AUTHOR> tag
containing the string 'ActiveState'. On a successful search, the package
name and the matching string are displayed.

=head1 ENVIRONMENT VARIABLES
=over 4
=item HTTP_proxy
If the environment variable 'HTTP_proxy' is set, then it will
be used as the address of a proxy server for accessing the Internet.
The value should be of the form: 'http://proxy:port'.

=head1 FILES
The following files are fully described in the 'Files' section of PPM:ppm.
=over 4
=item package.ppd
A description of a software package, in extended Open Software Description
(OSD) format. More information on this file format can be found in
PPM::ppd.
=item ppm.xml - PPM data file.
An XML format file containing information about the local system,
specifics regarding the locations from which PPM obtains PPD files, and
the installation details for any package installed by ppm.
This file usually resides in '[perl]/site/lib'. If the environment
variable 'PPM_DAT' is set, its value will be used as the full pathname
to a PPM data file. If all else fails, ppm will look for a data file
in the current directory.
