Options are:
-H REGEX filter messages by matching against head
-M REGEX filter messages by matching against body
-T NAME restrict to given theories (multiple options possible)
-U output Unicode symbols
-m MARGIN margin for pretty printing (default: """ + margin + """)
-o OPTION override Isabelle system OPTION (via NAME=VAL or NAME)
-v print all messages, including information etc.
Print messages from the build database of the given sessions, without any
checks against current sources nor session structure: results from old
sessions or failed builds can be printed as well.
Multiple options -H and -M are conjunctive: all given patterns need to
match. Patterns match any substring, but ^ or $ may be used to match the
start or end explicitly.
