BUILD.WWW.MK(5) 	       File Formats Manual		 BUILD.WWW.MK(5)

NAME
     build.www.mk -- bsdbuild - HTML document preprocessing

SYNOPSIS
     .include <bsd.www.mk>

DESCRIPTION
     The build.www.mk module is used to generate a set of HTML documents in dif-
     ferent  languages	and  character set variants from an HTML source file and
     one or more templates using the m4(1) macro processor in  conjunction  with
     the xsltproc(1) XSLT processor.  The following source types are recognized:
     *	 HTML+M4 documents (*.htm)
     *	 Cascading style sheets (*.css-in)
     *	 M4 macro packages (*.m4)

     From those sources, build.www.mk is able to generate:
     *	 Cascading style sheets (*.css)
     *	 HTML documents in multiple languages/character sets
     *	 HTTP variant data (*.html.var)

TARGETS
     ${HTML}	     Source  from  which to generate HTML documents (may include
		     M4 macro calls and use optional XSL transforms).

     ${CSS}	     Source from which to generate cascading style  sheets  (may
		     include M4 macro calls).

     clean-www	     Clean up the generated files.

     cleandir-www    Clean up for packaging.

     install-www     Install HTML documents to the target installation directory
		     HTMLDIR,	 overwriting	any    existing    document   if
		     HTML_OVERWRITE is `Yes'.  If HTML_INSTSOURCE is `Yes',  all
		     files  needed  for re-generating the documents are also in-
		     stalled into the target directory (including a Makefile).

     deinstall-www   Uninstall documents from the installation directory.

VARIABLES
     HTML	      Documents to generate and install.  If  multilingual  sup-
		      port is not required, use the .html extension.  Otherwise,
		      specify  the .html.var extension (documents will be gener-
		      ated for each combination of language and character set --
		      the .html.var file may then be used directly  by	Apache's
		      mod_negotiation or equivalent).

     M4 	      Path to the m4(1) macro processor.

     M4FLAGS	      Extra flags to pass to m4.

     XSLTPROC	      Path to the xsltproc(1) XSLT processor.

     PERL	      Path to the perl(1) interpreter.

     ICONV	      Path to the iconv(1) utility, needed to generate the char-
		      acter set variants.

     BASEDIR	      Directory containing the macro files (Default = "m4").

     XSLDIR	      Directory  containing XSLT source files (Default = "xsl").
		      Note that ml.xsl is required for multi-lingual support.

     DTD	      DTD to specify at the beginning of the generated	document
		      (default to HTML 4.01 Transitional).

     TEMPLATE	      Template	to  use  for  preprocessing the HTML source.  It
		      must reside in BASEDIR and use the .m4 extension.

     CSS_TEMPLATE     Similarly to TEMPLATE, but used to preprocess CSS source.

     LANGUAGES	      Space-separated list of  translations  available	for  the
		      documents   specified   in   ${HTML}.    See  the  section
		      "MULTI-LINGUAL SUPPORT" for more details.

     DEF_LANGUAGE     The default language.

     XSL	      Space-separated list of XSLT stylesheets to apply  to  the
		      documents (Default = "ml.xsl").

     CLEANFILES       Extra files to remove in the `clean' target.

     HTMLDIR	      Installation  directory.	 The  special value `none' indi-
		      cates that the `install' operation should be a no-op  (De-
		      fault = "none").

     HTML_OVERWRITE   Don't  overwrite existing documents in the `install' phase
		      (Default = "No").

     HTML_INSTSOURCE  Install the HTML source, templates, XSLT	stylesheets  and
		      all other files needed to be able to re-generate the docu-
		      ments in the installation directory, including a Makefile.
		      (Default = "Yes").

MULTI-LINGUAL SUPPORT
     The LANGUAGES variable specifies a list of languages in which the documents
     specified	in  HTML are available.  Since the ml.xsl XSLT stylesheet is ap-
     plied by default, HTML documents (usually encoded	in  UTF-8)  can  contain
     multiple  translations in a single file.  Language-specific parts are sepa-
     rated using the `<ml>' tag, like so:

	     <ml lang="en">Hello</ml>
	     <ml lang="fr">Bonjour</ml>
