-----------------------------------------------+----------------------------
 When the envcan.pl script is run with perl -w (i.e. warnings), a bunch of
 harmless uninitialized variable warnings are printed on standard error.
 This may confuse some to believing the script isn't working.

 To fix this, I've added checks to see if certain hash keys exist before
 they are checked for values.
