+Information options:
+  --help        Prints this text
+  --query=X     Shows the value of setting X. Possible settings are
+                include_path, configure_command, src_path, bin_path,
+                make and specs.
+
+Stage selection:
+                If none of these stages are selected, all of them will
+                be run, given that the timestamps of the dependncies
+                indicates that it is needed. If one or more stage is
+                selected, these stages will always run, but none of
+                the unselected ones.
+
+  --automake    Runs aclocal and automake.
+  --autoheader  Runs autoheader.
+  --autoconf    Runs autoconf.
+  --configure   Runs configure.
+  --depend      Runs make depend and make Makefile.
+  --make        Runs make.
+  --all         Runs all of the above.
+  --auto        Sets all stages to auto (default).
+
+Environment:
+  --source=X    Path to the source directory.
+  --configure-args
+                Additional arguments to configure.
