Scratch - Shell Script Part 1

#!/bin/sh
set -e

# Version 0.6c, 2007-06-21
# - Updated 2007-06-21 by Eric Lannert (eric.lannert@gmail.com)
# - added openldap, openssl, and bdb
# - changed flow to package by package - I found the need to run in pieces and wanted
# to make it easier for future add-on's
# - added switch to choose whether to delete source directory as this prevents incremental installs
# and recovering from errors
# - NOTE - I do not know where oracle's ftp is for the bdb, so the script assumes you
# have downloaded via http and uploaded by hand
# - abstracted wget_source to a reusable function
# - added LD_LIBRARY_PATH, CPPFLAGS, and LDFLAGS to chk_prepare
# - Updated 2007-06-08 by Chris Shymanik (chris@chipsncheese.com)
# - Will backup and re-install any old php.ini's found (see notes in wiki about this).
# - Source file detection.
# - Allows cgi-bin to be installed in a sub-directory (EXTDIR)
# - Created steps as functions, for easier troubleshooting/modification.
# - Updated various packages and did some additional code cleanup.
# - OSSP mm (Shared Memory Allocation) and bzip2 packages added.
# - Changed which binary to use, based on the new location in PHP 5.2.3.
# - Updated 2007-01-15 by Charles Wiltgen (charles@wiltgen.net)
# - Make "nicer" to help keep it from getting killed by DreamHost
# - Make less verbose to keep signal-to-noise level high
# - Updated 2006-12-25 by Carl McDade (hiveminds.co.uk)
# - Allow memory limit and freetype

#### User Configuration Options
## Domain & Directory Configuration
# Domain to install to
export DOMAIN="events.icstars.org"
# Temporary source directory
SRCDIR=${HOME}/source
# Download temporary DIST files to which directory?
DISTDIR=${HOME}/dist
# Delete contents of DISTDIR after installation? (Default: No)
DISTDEL="No"
# Delete contents of SRCDIR after installation? (Default: No)
SRCDEL="No"
# Backup your previous php.ini files to which directory (if any)?
# Please Note: You'll need to remove this directory manually if it's used.
# (!!You MUST use a trailing slash when specifying this directive!!)
BACKUPDIR=${HOME}/php5tmp/
# Install PHP5 to which directory?
INSTALLDIR=${HOME}/php5
# Install PHP5's cgi-bin files to a directory besides home?
# ie.: /home/username/mywebsite.com/sub/level/directory
EXTYESNO="No"
# Directory under home in which the cgi-bin files will be installed to
# ie.: /sub/level/directory
EXTDIR=main
# Nice Level for Processes. (Deprecated)
# Higher is nicer, lower is less nice and could get your install process killed!
NICE=19
