| Commands that need to modify the running user structure defined in scli.h |
| should reside here. They (will) have a slightly different prototype that |
| allows passing the user structure to them for ease of modifications. |
| Examples of what should be a built-in and not a module would be: |
| cd (cliuser_t->cwd needs to be updated) |
| In the future, more user preferences will be set via built-in commands, |
| such as the formatting of the prompt string (HelenOS doesn't yet have |
| an environment, much less PS*, even if it did we'd likely do it a little |
| differently). |
| .... etc. |
| Anything that does _not_ need to use this structure should be included |
| as a module, not a built in. If you want to include a new command, there |
| is a 99% chance that you want it to be a module. |
