+
+5.3 For the AliRoot user
+------------------------
+To install all libraries in the AliRoot lib dir:
+
+ mkdir build
+ cd build
+ ../configure --prefix=$ALICE_ROOT
+ make
+ make install
+
+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-doc # disable creation of doxygen documentation
+ --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
