+TeX Live Manager Shell
+======================
+
+to be written
+
+after starting, tlmgr shell echos out the protocol version
+	$ tlmgr shell
+	protocol NNN
+where NNN is a natural number, increasing when some commands
+are added, changed.
+
+Question:
+Handling of settings: e.g., how to mimic --repository and how
+to distinguish it from settings to be saved into the tlpdb.
+(--repository is used only for one incantation, but not saved
+into tlpdb)
+
+Commands: 
+---------
+* set
+  sets some variables not to be saved into the tlpdb
+	set repository ...	== --repository
+	set gui-lang LL		== --gui-lang
+	set debug-translation 1	== --debug-translations
+	set machine-readable 1	== --machine-readable
+	set no-execute-actions 1 == --no-execute-actions
+	set package-logfile ..	== --package-logfile
+	set persistent-downloads 0|1 == --(no-)persistent-downloads
+	set pin-file ...	== --pin-file
+	set require-verification 0|1 == --(no-)require-verification
+	set usermode 1		== --usermode
+	set verify-downloads 0|1 == --(no-)verify-downloads
+
+* quit|end|byebye
+  ends the session
+
+* load local|remote
+  loads the local or remote database
+  the remote tlpdb is determined by either the setting in the
+  loaded local tlpdb, or by the "repository" setting (see above)
+
+* save 
+  saves the local tlpdb (this is also done by several actions)
+
+All other actions are converted to commands and behave in the 
+absolut same way.
