Upgrade_Eggdrop_Ver_1.1_Keep_UTF-8.sh at work

#!/bin/sh
#
# Script written by AndrzejL. Sed lines by Enlik.
#
# I assume that:
#
# - You have a brain. ;)
# - The brain belongs to You. :D
# - You know how to use Your brain. ;D
# - You have installed all the eggdrop's dependencies.
# - You have installed and configured eggdrop 1.8 and it sits in ~/eggdrop folder. (1)
# - You want / need UTF-8 support.
# - You want to automate the process of upgrading the bot without a fuss.
#
# Script is partially based on http://eggwiki.org/Utf-8
#
# Script is intended to be run as a non-root user.
#
# Want to see how the script works? http://pastebin.com/97H4P7CE
#
# Script's purpose: upgrade Eggdrop 1.8 and ensure the use of the UTF-8 in 17 easy steps:
#
# 01 Switch to user's ~ folder.
# 02 Remove user's ~/.ccache to assure clean compilation.
# 03 Remove previous snapshot archive from user's ~ if there is one.
# 04 Remove previous compilation folder from user's ~ if there is one.
# 05 Download latest eggdrop-develop snapshot tarball directly to user's ~ folder.
# 06 Extract tarball to ~/eggdrop-develop folder.
# 07 Modify (thanks to Enlik) file ~/eggdrop-develop/src/main.h to ensure UTF-8 support.
# 08 Modify (thanks to Enlik) file ~/eggdrop-develop/src/tcl.c to ensure UTF-8 support.
# 09 Enter the ~/eggdrop-develop folder.
# 10 Run ./configure.
# 11 Run make config.
# 12 Run make static.
# 13 Run make install.
# 14 Kill currently running eggdrop process.
# 15 Switch to ~/eggdrop folder
# 16 Wait 10 seconds.
# 17 Start the bot again.
#
# Script is documented and commented while it runs with echo prints.
# You will notice that all the comments are in blue on a white background.
# You will notice that after each step a command "date" is invoked
# this way You can check how long did it took from the start of the script
# to the moment that the job is done. Some of You may find it useful.
#
# (1) As a side note: script _can_ be used to install fresh copy of eggdrop 1.8
# however the bot will not start until it's properly configured.
# For more info about configuring / troubleshooting eggdrop visit: http://eggwiki.org/
# or #eggdrop IRC channel on Freenode. This can be done using browser:
# http://webchat.freenode.net/?channels=eggdrop&uio=ND10cnVlJjEyPXRydWU91
# or IRC client of Your choice.
#
# I am not an eggdrop expert thus I am not willing / able to provide support for it.
