# Hello, *nix user! this is a frightfully simple but infinitely helpful SMPTE timecode converter. 
# It is a shell script that you must run from a unix terminal.  
# Don't know how to run a shell script?  It's easy!
#
# First, do this:
# bash$ chmod +x smpte.sh
#
# That just made the shell script executable.  From now on, you can use smpte.sh by typing in:
#
# bash$ ./smpte.sh
# 
# ...but you must do that ONLY from the directory the shell script is in.
###
# To make it even more flexible, you should create a "bin" folder in your home directory, add that "bin" to your path, and then you can run the shell script from anywhere.
#
# To do this, make a new directory in your home directory and call it bin.
# bash$ cd ~
# bash$ mkdir bin
# 
# Then copy the smpte.sh file into bin.
#
# Finally, add the bin to your path (replace "username" with your username):
# bash$ PATH=$PATH:/home/username/bin
# bash$ export PATH
# 
# You may need to close and re-open your terminal or logout or some series of weirdness, 
# depending on what hacker threw together your distro, and if you're on OS X then it wont work anyway
# but sooner or later you'll have access to smpte.sh from anywhere on your system.
#
# Enjoy!
