to permitted operations. By this option you can declare which opcode (or opcode tag) is
permitted. Please see the B<Safe> and B<Opcode> manual pages for further details. (These modules
come with perl.)

Pass C<ALL> to allow I<everything>.

This option can be used multiply.

You may want to store these options in default option files, see below for details.


For the examples used in I<ppdoc.pp> you should use

 --safeOpcode=:filesys_open --safeOpcode=:still_to_be_decided --safeOpcode=:browse


=item --set=flag

This option allows you to pass certain settings - of your choice - to active contents
(like conditions) where it can be accessed via the $PerlPoint hash reference. For
example, your PerlPoint code could contain a condition like

  ? $PerlPoint->{userSettings}{special}

  Special part.

  ? 1

The special part enclosed by the two conditions would then be processed I<only> if you
call C<pp2html> with

  --set special

and if active contents was enabled by I<-active>, of course.

This option can be used multiply.

=item --trans_table=filename

The C<--trans_table> option specifies a the filename of a tanslation table
for non ASCII characters like german Umlaute etc. The characters are
specifed as octal numbers as in the folowing example:

  #Translation Table for German Umlaute (this is the default)

  \334 &Uuml;
  \374 &uuml;

  \326 &Ouml;
  \366 &ouml;

  \304 &Auml;
  \344 &auml;

  \337 &szlig;


=item --filter=regexp

This specifies a regular expression C<regexp> which should match
all allowed languages for EMBEDed code. The expression is evaluated
caseinsensitively.

Example: --filter="perl|html"

=item --nocopyright

suppresses the copyright message;

=item --noinfo

supresses runtime informations;

=item --nowarn

supresses warnings;

=item --quiet

a shortcut for "--nocopyright --noinfo --nowarn": all non critical runtime messages are suppressed;

=item --count_only

If this option is set, only a counter will indicate that slides are created. Otherwise 
for all slides the full header is printed while generating the slides.


=item --box_color=color

=item --boxtext_color=color

Set background and forground colors for block paragraphs


=item --bgcolor=color

=item --fgcolor=color

=item --idx_bgcolor=color

=item --idx_fgcolor=color

=item --toc_bgcolor=color

=item --toc_fgcolor=color

=item --top_bgcolor=color

=item --top_fgcolor=color

=item --bot_bgcolor=color

=item --bot_fgcolor=color

=item --linkcolor=color

=item --alinkcolor=color

=item --vlinkcolor=color

Set the background and foreground color for all HTML pages. The C<idx_> and C<toc_> options
