***  Short Explanation of Purpose of Files  ***

README                            gives an overview of all files in this directory
all_known_solutions               all (to me) known no-three-inline problem
                                  solutions aka. valid configurations
configurations                    directory where each file contains the known
                                  solutions for a fixed gridsize n and a fixed
                                  symmetry (iden,dia1,rot2,ort1,rot4,rct4,dia2,
solutions_by_symmetry             directory which contains 9 directories for the
                                  9 (pseudo-)symmetries iden,dia1,rot2,ort1,
                                  rot4,rct4,dia2,ort2 and full, each containing
                                  the known solutions for a given grid size
no3in_functions.c                 commonly used routines to manipulate solutions
no3in_functions.h                 header file for no3in_functions.c
db_count.c                        to make a statistic of a file of solutions
decode_check_normalize_compare.c  to decode, check, normalize, compare and store
                                  possible solutions read from a given file or
                                  from stdin (it stores only if option -S is
                                  given and the solution is not in the database)
decode_check_normalize.c          to decode, check, normalize possible solutions
                                  read as command parameter/strings
fullnew.c                         the C-program which generates all full
                                  symmetric solutions (I continued this year
                                  the search up to all n <= 98. Previously I
                                  had only searched up to n <= 82)
iden.c                            the C-program which generates all solutions
