Heyla,
  just a small patch to provide some emulations for csh/tcsh functions:
  glob, printenv, setenv, unsetenv, and a sample filetest (which could use
  quite a bit of improvement in checking options).  There are a couple of 
  others I was thinking of doing to ease any transition from tcsh.
  (BTW, anyone ever seen glob or filetest used?)

Note:
  In StartupFiles, all the files have a header line like
  Generic .zshrc file for zsh 2.7
  Umm, which version?

Question:
  Also, the parsing with [[ is a bit strict.  I had to use [ in filetest.
  Is it due to the order of parsing [[ coming before variable expansions
  or some such?  Maybe one of these years I'll have time to learn how
  zsh works!
