Hi, I have several .*qbk files that I build in separated folders, each one with is own index.html. However, I couldn't make that one of them to be the main root so when I click in home button it goes to the main root, independently from which file I am. I could only manage to get up and home button to go to file's own index. There's any solution for this or I must build everything in the same file? This is my jamfile: project doc ; import boostbook : boostbook ; xml mainXml : src/main.qbk ; xml clientXml : src/app/client.qbk ; xml serverXml : src/app/server.qbk ; boostbook main_base : mainXml : <xsl:param>boost.image.src="./images/logo.png" <xsl:param>boost.image.w=100 <xsl:param>boost.image.h=100 <xsl:param>nav.layout=none <xsl:param>base.dir=../doc/html/ <xsl:param>root.filename=index <xsl:param>html.stylesheet=./style.css <xsl:param>generate.manifest=0 ; boostbook client : clientXml : <xsl:param>boost.image.src="./../../images/logo.png" <xsl:param>boost.image.w=100 <xsl:param>boost.image.h=100 <xsl:param>nav.layout=none <xsl:param>base.dir=../doc/html/app/client/ <xsl:param>root.filename=index <xsl:param>html.stylesheet=./../../style.css <xsl:param>generate.manifest=0 ; boostbook server : serverXml : <xsl:param>boost.image.src="./../../images/logo.png" <xsl:param>boost.image.w=100 <xsl:param>boost.image.h=100 <xsl:param>nav.layout=none <xsl:param>base.dir=../doc/html/app/server/ <xsl:param>root.filename=index <xsl:param>html.stylesheet=./../../style.css <xsl:param>generate.manifest=0 ;
