+## Build a list of unit tests.
+##
+## Conditional tests (external dependencies) can be handled
+## automaticaly.  For each dependency, a file named
+## "cond_tests_{DEPS}" must contain the list of files which need the
+## dependency.  If a test needs more than one dependency, several
+## dependency names can be used in the file name.
+##
+## Ex: cond_tests_qt_tesseract
+##
+## All the tests listed in this file will need both qt and tesseract
+## to be compiled.
+##
+## "cond_tests_*" files must be created in the directory where
+## unit-test.mk is generated (usually the unit-tests directory).
+##
+## WARNING: don't forget to add "cond_tests_*" files in the COND_TESTS
+## variable in the right Makefile.am.
+
 ## FIXME: Don't use `echo -n', as echo's options are not portable.
