Oracle does not support Perl's dynamic loading of modules, so you need to
specify at compile time which modules you want to use.  This does not apply
to Perl-only modules, but you can enter them here anyway if you are unsure,
and they will be ignored.  ExtProc is automatically included, so you don't
need to specify it here.  Type "+" first if you want to add to the default
list instead of replacing it (e.g. "+Authen::Krb5 HTML::Parser").  Remember,
you can always update this list and relink later.

NOTE: If you are using Oracle 9.2.0 or higher, external procedure libraries
must must be located in \$ORACLE_HOME/lib or else you will need include the
path to the each library in the EXTPROC_DLLS environment variable for your
listener.  Failure to do this will result in an ORA-28595 error.  See Oracle
documentation for details.

extproc_perl can parse a global bootstrap file that contains Perl code shared
by all sessions.  You can use it to store common subroutines or data, even
system-specific data, as it lives in the file system rather than the database.
If you do not want this feature enabled at all, type 'none' (without the
quotes).

_DONE_

print "Path to bootstrap file [$DEFAULT_BOOTSTRAP]: ";
my $bootfile = <STDIN>;

extproc_perl will query the calling database for a Perl subroutine if it
doesn't exist in the bootstrap file.  Specify the default table to query here.

You can import code into the database from various files.  For security, these
files will only be imported from one directory, called the "trusted code
directory".
