In some case, it would be nice to get the environment variable set in the process that launched kazimir. I mean the variables
defined in the calling shell by setenv VAR VAL in csh or export VAR=VAL in ksh.
Kazimir defines an implicit hash table called $(ENV[]) which contains all the caller's environment.
For example, $(ENV[PATH]) contains the value of the shell's path. Using this hash allow closer interaction between kazimir and its caller.
