Subject: Add makefile target to update HTML files in source tree
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e81486bd394b0a44dedb6c3e2592e13ea6d0b1a0;p=thirdparty%2Fgcc.git

Add makefile target to update HTML files in source tree

Also remove the creation of the html/ext sub-directory, which has been
unused since revision r245258.

	* doc/Makefile.am (doc-html-docbook-regenerate): New target.
	(${docbook_outdir}/html): Do not create unused 'html/ext' directory.
	* doc/Makefile.in: Regenerate.
	* doc/xml/manual/documentation_hacking.xml: Document new target.
	* doc/html/*: Regenerate.
