Hi, I have several *.qbk files and I want to build documentation of all of them at one time. They are all in the same folder, so I use the same Jamfile for each one: *using quickbook ; import boostbook : boostbook ; # Intro xml intro : src/intro.qbk ; # Libraries xml base_lib : src/libs/base.qbk ; # App xml client : src/app/client.qbk ; boostbook documentation : intro : <dependency>css ; boostbook lib : base_lib : <dependency>css ; boostbook client : client : <dependency>css ; install css : [ glob ./*.css ] : <location>../html ; explicit css ;* However, they have been building at the same root folder. That fact left me only one index file, because the previous one have been overwrite. How can I resolve it? Thanks
