+
+5.4 Package options
+-------------------
+Some important options (all options are on by default):
+
+ --disable-sample # disable compilation the sample library
+ --disable-util # disable compilation the util library
+ --disable-tpc # disable compilation the TPC library
+ --disable-phos # disable compilation the PHOS library
+ --disable-trd # disable compilation the TRD library
+ --disable-dimuon # disable compilation the MUON library
+ --disable-aliroot-logging # disable logging
+ --disable-strict # disable strict coding conventions and
+ compilation flags
+
+All detector libraries (including sample and util lib) require AliRoot,
+compilation is disabled if no working AliRoot version was found. This can
+occur even if an AliRoot version is set up correctly since the configure
+script checks for the usability of the AliRoot libraries (mainly STEER and
+the ones it depends on). If new dependencies are introduced, the check
+might fail.
+
+Compilation of detector libraries can be forced by the switch
+
+ --enable-detector, e.g. --enable-phos
+
+Compilation can also be forced by typing 'make' in the detector
+sub-directory.
+
+Debugging (default disabled)
+
+ --enable-debug # enable debugging: symbols & messages
+
+Optimization (default -O2)
+
+ --disable-optimization # disable compiler optimization
+ --enable-optimization<=l> # enable compiler optimization level l
+
+5.5 External packages
+---------------------
+PubSub framework: the TPC online display needs the HOMER interface, which
+is currently part of the PubSub framework. It is planned to integrate it
+into AliRoot.<br>
+If the TPC online display is not necessary one can skip this option.
+
+ --with-pubsub=<dir> # the top dir of the HLT PubSub framework
+
+5.6 Final remarks/further information
+-------------------------------------
+\b Note: You can have several build directories with different configure
+options, but using the same source code.
