Usage: isabelle imports [OPTIONS] [SESSIONS ...]
Options are:
-B NAME include session NAME and all descendants
-D DIR include session directory and select its sessions
-I operation: report session imports
-M operation: Mercurial repository check for theory files
-R operate on requirements of selected sessions
-U operation: update theory imports to use session qualifiers
-X NAME exclude sessions from group NAME and all descendants
-a select all sessions
-d DIR include session directory
-g NAME select session group NAME
-i incremental update according to session graph structure
-o OPTION override Isabelle system OPTION (via NAME=VAL or NAME)
-v verbose
-x NAME exclude session NAME and all descendants
Maintain theory imports wrt. session structure. At least one operation
needs to be specified (see options -I -M -U).
