#

# Automatically download all the files needed to run the "pear" command

# (the PEAR package installer).  Requires PHP 4.1.0 or newer.

#

# Installation: Linux

#

# This script can either be directly launched or passed via lynx like this.

#

#  $ lynx -source http://pear.php.net/go-pear | php

#

# The above assumes your php binary is named php and that it's

# executable through your PATH:

#

# Installation: Windows

#

# On Windows, go-pear uses stdin for user input, so you must download

# go-pear first and then run it:

#

# Note: In PHP 4.2.0-4.2.3, the PHP CLI binary is named php-cli.exe while since

# PHP 4.3.0, it's simply named php.exe in the cli/ folder of your PHP directory.

# The CGI is also named php.exe but it sits directly in your PHP directory.

#

#  > cli/php -r "readfile('http://pear.php.net/go-pear');" > go-pear

#  > cli/php go-pear

#

# In PHP 5.0.0, the PHP CLI binary is php.exe

#

#  > php -r "readfile('http://pear.php.net/go-pear');" > go-pear

#  > php go-pear

#

# Installation: Notes

#

# - If using the CGI version of PHP, append the -q option to suppress

#   headers in the output.

# - By default, go-pear will install a system-wide configuration file.  For

#   a local install use:

#   > php go-pear local

#

# - Once the go-pear script is initiated, you will see instructions on

#   how to continue installing PEAR.  The first thing you should see is:

#

#   Welcome to go-pear!

#

# Installation: Web browser

#

# You can now use go-pear via a webbrowser, thanks to Christian Dickmann. It is

# still beta codes, but feel free to test it:

# 1.: Download the go-pear script by using the "Save target as ..." function

# of your browser here.

#

# 2.: Place the go-pear file somewhere under the document root of your webserver.

# The easiest way is to create a new directory for pear and to put the file in there.

# Be sure your web server is setup to recognize PHP, and that you use an appropriate

# extension.  For example, you might name this file gopear.php

#

# 3.: Access go-pear through your webserver and follow the instructions. Please

# make sure that PHP has write access to the dir you want to install PEAR into.

# For example: http://localhost/pear/gopear.php

#

# 4.: After running go-pear you get a link to the Web Frontend of the PEAR installer.

# I suggest bookmarking this link.

#

# 5.: Protect the Web Frontend directory and the go-pear script with a password.

# Use .htaccess on Apache webservers for example.

#
