Jeez!  What was I thinking?

You can easily do what you want by including the following line near the 
beginning of your script:

. ~/.bashrc

The leading dot and space are important.  They are shorthand for the source 
command.  Source reads a file and includes it in your script.  It is useful 
for including libraries of common functions, constants, etc.

This will work your scripts but probably would not be useful for scripts 
shared by other users.  To solve this problem, you should look at /etc/bashrc 
and /etc/profile files which provide the common environment for all users.
