Typically the variables that matter are those that affect how commands you've
given are found, like PATH. It's rare to require access to allot of other
environment variables for proper running and certainly it's buggy to build
your own scripts that rely too much on environment variables. Obviously, if
you do need some set, include them in the script that cron will run. But
you are better off providing full paths to executables in your cron scripts,
as Igor notes, and going without all the added complication of setting PATH.
If you have special needs to set variables, then the variables involved
are likely to be either immediately obvious or self-evident after reviewing
the man/info page for the utilities in use.
