More specifically: + +=over 4 + +=item * + +It checks if all the files referenced by F<searchindex.js> exist. + +=item * + +It replaces known F<*.js> files with symlinks to F</usr/share/javascript/sphinxdoc/> +and generates B<${sphinxdoc:Depends}> substitution variable. + +=item * + +If the Sphinx RTD theme is used, it replaces known files from this theme with +symlinks to F</usr/share/sphinx_rtd_theme/>, and adds B<sphinx-rtd-theme-common> +to B<${sphinxdoc:Depends}>. + +=item * + +It provides a B<${sphinxdoc:Built-Using}> substitution variable, for tracking +files which could not be symlinked. Examples of such files are F<*.js> and F<*.css> +files that are generated from corresponding F<*.js_t> and F<*.css_t> templates, +and can vary depending on the used theme options (for instance, F<basic.css> file +is generated from F<basic.css_t> and is included in almost every Sphinx-generated +documentation). Currently, this variable will contain B<sphinx> and, if the default +theme is used, B<alabaster>, with their versions (other themes are not supported). + +=item * + +It removes the F<.doctrees> directory. + +=item * + +It removes the F<.buildinfo> file. + +=item * + +It removes the F<websupport.js> file. + +=back + +Note that B<dh_sphinxdoc> does not build the documentation, it only performs +the above operations when the documentation is already installed into the +package build path. To build the docs, please use L<sphinx-build(1)> command +or B<python3 -m sphinx> syntax. + +You can pass B<--with sphinxdoc> to L<dh(1)> to make it automatically call +B<dh_sphinxdoc> after B<dh_installdocs>. + +=head1 OPTIONS + +=over 4 + +=item I<directory> + +By default, B<dh_sphinxdoc> scans your package looking for directories looking +like they contain Sphinx-generated documentation. However, if you explicitly +provide one or more directories, only they will be processed. If documentation +is not found at I<directory>, an error is raised. + +=item B<-X>I<item>, B<--exclude=>I<item> + +Exclude files that contain I<item> anywhere in their filename from +being symlinked, removed or checked for existence. + +=back + +=head1 BUGS + +Symlinking translations.js is not supported. + +=cut + +use strict;
