+script/gen does all the magic. Run it with no arguments to get a
list of options. It takes the stylesheets wrapper.xsl, and those
inside the "web" and "doc" directories and creates a website from
them. You also tell it where to find spec.xml and filter.xml and it
## Example 1:
- script/gen.pl --latest 4.72 --web --tmpl templates --docroot /var/www/
+ script/gen --latest 4.72 --web --tmpl templates --docroot /var/www/
This copies all of the files from the "templates/web" directory
into "/var/www/". When it comes across .xsl files, it generates
## Example 2:
- script/gen.pl --latest 4.72 --spec docbook/*/spec.xml \
+ script/gen --latest 4.72 --spec docbook/*/spec.xml \
--tmpl templates --docroot /var/www/
If there are multiple spec.xml files in "specs/*/" for different
## Example 3:
- script/build.sh /var/www/
+ script/build /var/www/
Generates everything into output directory /var/www
-Look at the script/build.sh for details - it is just a wrapper
-around build/gen.pl

All of the above examples make sure the exim-html-current symlink
on all pages, you would need to re-generate *all* web pages. This
is a drawback of having a static website without frames. You would
only need to edit one file though, specifically wrapper.xsl. Once
-that is done, you would run gen.pl with --web, --spec and --filter,

providing the filter.xml and spec.xml files for every piece of
online documentation.

+
+List of files that make up the specification documentation docbook/XML source
+files.
+
+=item B<--filter> I<file...>
+
+List of files that make up the filter documentation docbook/XML source files.
+
+=item B<--web>
+
+Generate the website from the template files.
+
+=item B<--latest> I<version>
+
+Specify the current exim version. This is used to create links to the current
+documentation.
+
+This option is I<required>
+
+=item B<--tmpl> I<directory>
+
+Specify the directory that the templates are kept in.
+
+This option is I<required>
+
+=item B<--docroot> I<directory>
+
+Specify the directory that the output should be generated into. This is the

+
+This option is I<required>
+
+=item B<--minify>
+
+If this option is set then both the CSS and Javascript files processed are
+minified using L<CSS::Minifier::XS> and L<JavaScript::Minifier::XS>
+respectively.
+
+This option is set by default - to disable it specify C<--no-minify>
+
+=item B<--localstatic>
+
+Makes the static files (CSS, images etc), local for each version of the
+documentation. This is more suitable for packaged HTML documentation.
