 check     - Build veil and run regression tests\n\
 clean     - remove target and object files\n\
 deps      - Recreate the xxx.d dependency files\n\
 docs      - Build veil html docs (requires doxygen and dot)\n\
 help      - show this list of major targets\n\
 install   - Install veil\n\
 list      - show this list of major targets\n\
 regress   - same as check\n\
 regress_clean - clean up after regression tests - (drop regressdb)\n\
