frame affects printing messages on entry and exit from subroutines.
AutoTrace affects printing messages on every possible breaking point.
maxTraceLen gives maximal length of evals/args listed in stack trace.
+ ornaments affects screen appearance of the command line.
During startup options are initialized from \$ENV{PERLDB_OPTS}.
You can put additional initialization options TTY, noTTY,
- ReadLine, and NonStop there.
+ ReadLine, and NonStop there (or use `R' after you set them).
< command Define Perl command to run before each prompt.
