Adding $ucsc_bin to \$PATH.
UCSC kent utils contains commands that conflict with other tools, including
at least "calc", "mktime", and "stringify".
The other commands with these names may serve entirely different functions
and will not be accessible while running this shell unless you refer to them
by their absolute path name (e.g. /usr/local/bin/calc), which is not portable,
BTW, so don't hard-code such paths into your scripts.
Type "exit" or "Ctrl+D" to return to your normal shell.
