# ref is a plugin for storing HTML formatted references, mainly suited for programming. 																			
# Your $REF_DIR variable is the directory for storing these references in. If it does not exist, it will be created automatically. 									
# Here is an example of what my $REF_DIR looks like, because this will be of use when I explain how your $REF_DIR has to be structured: 							
# 																																									
# ~/.ref/ 																																							
#   ruby/ 																																							
#       general/ 																																					
#  			index.html 																																				
# 	bash/ 																																							
# 		array/ 																																						
# 			index.html 																																				
# 		select/ 																																					
# 			index.html 																																				
# 																																									
# This is what the basic structure of your $REF_DIR should look like: Subdirectories for each subject, and then another set of subdirectories for the part of the   
# subject you want to reference. And in the second subdirectory, an index.html file. 																				
# 
# To use ref, you do the ref command followed by the sugject and the sub-subject as arguments. For instance:
# 
# ref bash array
# 
# Would open the bash/array/index.html file.
# 
# To list your references, you would do the ref ls command, optionally followed by a subject. For instance:
# 
# ref ls
# 
# Would give me:
# 
# ruby bash
# 
# And:
# 
# ref ls bash
# 
# would output:
# 
# array
# select
# 																																									
# I hope that you like this plugin and if you have any questions about it, send me (mrman208) a message on GitHub or email me at mrman208@me.com
