#
# 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.
#

If your source is 4.3.x or newer, just make sure you don't run
'configure' with --disable-cli, rebuilt and copy sapi/cli/php.
