Some ideas for the commandline application:
```
# token related stuff, have interactive login (by default); non-interactive; conversion from kerberos (if possible?)
$em [global] token info
$em [global] token login [--refresh] [--(no-)interactive]
$em [global] token logout

# get info about an id
$em [global] info $id
[--all] # include all metadata
[--tree ?] # give a tree-view with resolved links (ie: createdBy, perhaps)

# download based on id; need a way to specify file format
$em [global] get $id

# register a file
$em [global] register --type $TYPE [--upload/--copy-to-storage] path/to/file

#list known types
$em [global] list-types

# simple search for items, w/ a $simple-query style
$em [global] search $simple-query [--dump-sparql]

Global:
-vv # verbose-ness
--staging # use staging
```
