 C<bundle> can load a new environment in current shell
-or load it in a sub-shell.
+(source) or load it in a sub-shell.
+In this second case, environment could be unload!
+
+This shell function looks furiously at the command C<module>.
+It's wanted but is much simpler (no C<tcl>...).
+The arguments are quite the same.
+There is no magic done on the current environment variables
+and it's possible to export shell functions which is not possible width C<module>
+(remember, C<bundle> just source shell file).
+
+C<bundle> launch a new shell (sub-shell) at load and exit it at unload.
+It's all!
+
+No...
+In interactive mode, it's save the current history so this one can be use in the sub-shell.
+The same thing is done at the end of the sub-shell,
+history is then reload in the master shell.
+For the user point of vu, it's like there is only one shell!
+
+But be carrefull width variable,
+only export variable could be use in sub-shell.
