+Prefixing \$PATH with $emboss_bin.
+
+Emboss contains commands that conflict with other tools, including at least
+"charge", "cons", "garnier", "prophet", and "tcode".
+
+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. %%LOCALBASE%%/bin/garnier), 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.
