+- mess with gcc performance optimization options (https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html)
 IN PROGRESS - concordia search zwraca pozycje tokenów z hash'a. Jak to odnieść do examples w korpusie?
 - testy zużycia pamięci
 - Prawdopodobnie długość example w markers będzie potrzebna tylko anubisowi (który, jak się okazuje, jest wolny). Pomyśleć, do czego można wykorzystać markery, bo ich idea wydaje się niezła.
 - Multi-threading? (przy concordia search jak najbardziej. Tylko wtedy trzebaby zastosować sortowanie po końcach przedziału przed liczeniem best overlay, co nawiasem mówiąc jest gotowe).
-- concordia-server (zastanowić się, czy nie napisać CAT-a oraz nad tym, czy nie oddzielić projektu concordia-server).

+DONE - concordia-server (zastanowić się, czy nie napisać CAT-a oraz nad tym, czy nie oddzielić projektu concordia-server).
+DONE - document the code
+DONE - prepare website (home, downloads, documentation, tutorial, issues, sourceforge page, about author)
+DONE - copyright libdivsufsort i psi-toolkit (in documentation)
+
 DONE - puścić 100% search test na jrc
 
 REJECTED - zastanowić się nad empty hash examples (rozwiązanie: w ogóle nie szukać fraz o pustym hashu, rzucać wyjątek).
