perl-debug - 5.32.1-4+deb11u3 main

debugperl provides a debug-enabled version of Perl which can produce
extensive information about the interpreter as it compiles and executes
a program (see the -D switch in perlrun(1)).
.
Note that this package is primarily of use in debugging *Perl* rather
than perl programs, which may be traced/debugged using the standard
perl binary using the -d switch (see perldebug(1)).
.
In addition, this package also includes debugging information for the normal
Perl interpreter.
