Editing WoW:Creating a slash command (section)

== Strategy ==
# Pick a unique identifier for the slash command: i.e. MYADDON
#: A common convention is ADDONNAME if you only have one slash command, or ADDONNAME_COMMANDNAME if you have multiple (where ADDONNAME is the name of your addon).
# Decide which slash commands you want to respond to: i.e. /myadd.
#: You can select multiple alternatives for the same command -- allowing shorter or longer command names to be used in case of conflicts.
# Assign your selected slash commands to SLASH_MYADDON1, SLASH_MYADDON2, etc global variables.
# Write a slash command handler function (taking (msg, editbox) as arguments), and place assign it to SlashCmdList["MYADDON"].

Here is a simple example that can be placed anywhere in a Lua file:
 -- 1. Pick HELLOWORLD as the unique identifier.
 -- 2. Pick /hiw and /hellow as slash commands (/hi and /hello are actual emotes)
 SLASH_HELLOWORLD1, SLASH_HELLOWORLD2 = '/hiw', '/hellow'; -- 3.
 function SlashCmdList.HELLOWORLD(msg, editbox) -- 4.
  print("Hello, World!");
 end
