#h space script by duus

##################################################### VERSION INFO
#v space, a bash wrapper for Spaces, v 0.1, by duus
#v
#v 	  type <space help> for more information
#v    or open source code with a text editor and read it:
#v    http://thedu.us/scripts/space/space/
#v
###################################################### INSTALL INFO
#i How to install space
#i  1. put the space bash script on your path (for example, ~/bin/)
#i  2. navigate to that directory
#i  3. type "chmod +x space" to make the script executable
#i  4. open the space script with your favorite text editor (pico space, for example)
#i  5. Navigate to the line called #SETTINGS
#i  6. Adjust settings as necessary.  Save the file.
#i  7. type "space help" for usage information
#i
###################################################### SETTINGS
# general settings; name and location of this script, for self-referencing.
_SCRIPT_NAME=space            
_SCRIPT_LOCATION=~/bin           
# you can also hardcode if you would like.  For example, your own bin:
# _SCRIPT_LOCATION=~/bin
# or, if you are running reuben, you can access reuben's bin:
# _SCRIPT_LOCATION=~/.reuben/.bin/
# don't forget that this program is merely a text file, and you must make 
#   it executable, regardless of where you place it.
# Script_Location is used in the standard functions, below.
#
###################################################### STD, FUNCTIONS (help, version, install)
#  (h)elp, (v)ersion, and (i)nstall are standard.  I do not recommend changing them.
#    Reading them, on the other hand, to see how they work is encouraged.
#    Feel free to add another standard function.  If you do, please let me know if it is useful,
#     and whether you would mind if I included it in the standard code, with credit for you
#     in comments.  (Or an about section?  .... hmmmm)
#    These functions allow the output of the standard functions to be 
#    hardcoded into the source code.  (See #i and #v above for examples.)
