-+.SH NAME
-+lifesearchdump - search for oscillators and ancestors of life patterns
-+.SH SYNTAX
-+.B lifesearchdump -r rows -c columns -g generations [options...]
-+.SH DESCRIPTION
-+This program attempts to find life objects which are periodic, which are
-+spaceships, or which are parents of a given object. (Ncurses)
-+.P
-+You specify a region to search in, the number of generations of interest, and
-+some initial cells. The program then searches for all objects which satisfy
-+the conditions. The search applies transition and implication rules which
-+restrict the number of possible objects considered to a small fraction of the
-+total number. This makes it practical to find these objects in a reasonable
-+amount of time. (Reasonable ranges from a few minutes to many days, depending
-+on the size of the search.)
-+.P
-+The algorithm used here is based on the one described by Dean Hickerson in a
-+document included with the xlife distribution. Reading that document will
-+explain how the search in this program works, except for minor changes.
-+.P
-+The program usually looks for an object which is periodic in the number of
-+generations specified by the -g option. For example, use -g3 to look for
-+period 3 oscillators or spaceships. The program is pretty fast for period 2,
-+satisfactory for period 3, long for period 4, and very long for period 5.
-+.P
-+By default, the program only finds objects which have the full period specified
-+by the -g option. Objects having subperiods of the full period are skipped.
-+For example, when using -g4, all stable objects or period 2 oscillators will
-+not be found. The -a command line option disables this skipping, thus finding
-+all objects, even those with subperiods. You probably want to use -a if you
-+use any of the -tr, -tc, or -p options.
-+.P
-+The object is limited to the number of rows and columns specified by the -r
-+and -c options. Cells outside of this boundary are assumed OFF. Thus if
-+any generation of the object would expand out of the box, then the object
-+will not be found. The program finds things quicker for a smaller number of
-+rows and columns. Searching proceeds from left to right column by column,
-+and within a column from middle to edge. It is quicker to search when there
-+are less rows than columns.
-+.P
-+The three command line options -r, -c, and -g are always required (unless
-+you are continuing a search using -l or -ln). If you do not specify these
-+options, or give them illegal arguments, a brief message will be output and
-+the program will exit. All other options are truly optional.
-+.P
-+If you want to find a symmetric object, then use the -sr or -sc options.
-+The -sr option enforces symmetry around the middle row if the number of rows
-+is odd, or the middle two rows if the number of rows is even. The -sc option
-+does the same thing for columns. You can specify both options to look for
-+fourfold symmetry. These options will speed up the search since fewer cells
-+need examining, but of course will miss all unsymmetric objects.
-+.P
-+Another way to speed up the search is to use the -m option to limit the
-+number of ON cells in generation 0. This will of course miss any
-+objects which have too many cells.
-+.P
-+By default, the program looks for purely periodic objects. To find a
-+spaceship, you must use the -tr or -tc options to specify a translation.
-+This makes generation N-1 shift right or down by the specified number of
-+cells in order to become generation 0. Thus this finds spaceships which
-+move leftwards or upwards. Use -tc to translate columns (thus making
-+horizontal ships), and -tr to translate rows (thus making vertical ships),
-+or a combination (thus making diagonal spaceships). The slowest ship for
-+any period uses a translation of 1, as for example -tc1. Remember that the
-+fastest horizontal speed is C/2 and the fastest diagonal speed is C/4, so
-+that for example, using -tc2 for a period 3 spaceship will find nothing.
-+.P
-+By default, the program looks for objects such that generation N-1 implies
-+generation 0, so that periodic objects can be found. The -p command line
-+option disables this circular dependency, so that generation 0 has no past
-+and generation N-1 has no future. This enables you to search for the parents
-+of any object you desire. Commonly you specify -g2 with this option, to
-+look only one generation back. To look for parents of an object, you specify
-+the cells of the object in generation N-1, and leave the earlier generations
-+unknown. The `c' command is useful with this option to completely specify
-+the last generation (see below).
-+.P
-+The search program is always in one of two modes. It is either in command
-+mode, or in search mode. When first started, it is in command mode.
-+Command mode is indicated by the presence of a "> " prompt. When in
-+command mode, you can enter commands to the program, one per line.
-+To leave command mode and begin searching, you simply enter a blank line.
-+You can get back to command mode again by generating the SIGINT signal.
-+When this is done, the program will stop searching at a convenient place,
-+display the lastest status of the search, and read commands again. Do not
-+forget to later type the blank line to continue searching again!
-+.P
-+When first started, you may wish to specify the state of some cells to
-+guide the search. You can specify that any cell in any generation should
-+be either ON or OFF. Cells that you do not specify remain unknown. As an
-+example, if you were looking for a period 3 oscillator, you might want to
-+specify the middle cell as being ON in generation 0, and OFF in generation 1.
-+This would force period 3 behavior. Note that when you specify cells, the
-+state specified is permanent. The program will not reverse your settings,
-+and therefore can not find any objects which do not match your settings.
-+Also note that settings unfortunately cannot be corrected, so if you set
-+the wrong cell by mistake, you must leave the program and start again.
-+.P
-+To specify a cell, you use the `s' command when in command mode. This command
-+takes 2 or 3 arguments. The first two arguments are the row and column
-+numbers of the cell to set. The third number is either 1 for setting the
-+cell ON, or 0 for setting the cell OFF. If the third number is omitted,
-+then ON is assumed. The cell is always set in the current generation, which
-+is the one last displayed. If necessary, you use the 'n' or 'p' commands
-+to change the current generation to the desired one before using the 's'
-+command. For example, if the currently displayed generation is generation 0,
-+entering "s 5 6" would set the cell at row 5 column 6 of generation 0 to ON,
-+whereas "s 2 7 0" would set the cell at row 2 column 7 to OFF. As a shortcut,
-+you can omit the 's' letter, so that the command "5 6" would set the cell at
-+row 5 column 6 ON. If you are using the -sr or -sc options for symmetry, you
-+don't have to enter the symmetric cells since the program does that for you.
-+.P
-+You can use the -i or -ia options to input the initial settings for either
-+generation 0 or the last generation instead of typing in their coordinates
-+manually as above. The setting is normally for generation 0, but if the
-+-p option was also used, then the setting is for the last generation. The
-+specified file contains a picture of the cells, with 'O' or '*' indicating
-+ON, '.' indicating OFF, and '?' indicating unknown. If you use -i, then
-+only the ON cells are set, making the OFF cells stay unknown. If you use
-+-ia, then both ON and OFF cells are set. You can still specify additional
-+cells after the ones in the file have been read.
-+.P
-+The `c' command will set all the currently unknown cells in the current
-+generation to the OFF state. This is intended to be used when searching
-+for parents of an object that you have entered, and you know exactly what
-+the object in the last generation looks like. This command requires
-+confirmation before it is acted on.
-+.P
-+Just before entering command mode, or occasionally if automatic viewing is
-+enabled, the program will display the current status of the search.
-+Cells marked as 'O' are ON, cells marked as '.' are OFF, and cells marked
-+as '?' are currently unknown. The generation number and the number of ON
-+cells are also given, along with some of the command line options that were
-+used to start the program.
-+.P
-+If you don't like to keep hitting interrupt in order to see the progress of
-+a search, you can tell the program to automatically display the object every
-+so often. This is done either with the -v command line option, or the `v'
-+command. The numeric argument is how many thousand search iterations to
-+perform between displays. As an example, the command line option -v1
-+displays about every 5 seconds for a 20MH 386.
-+.P
-+Normally if the program finds something, it will display the object and wait
-+for commands. At this point you can write out the object if desired. Typing
-+`N' will continue looking for further objects which work. If you specified
-+the -a command line option, then the `N' command will be needed immediately
-+after starting a search with no initial settings, since the state of all OFF
-+cells obviously satisfies all conditions.
-+.P
-+However, if you specify the -o option on the command line, the program will
-+NOT stop when it finds an object. Instead, it will append the found object
-+to the specified file name, and automatically keep looking for further
-+objects which work. The objects stored in the output file are separated
-+with blank lines. When no more objects have been found, the program will
-+print a final status message and exit.
-+.P
-+The following is a summary of all the commands available. The `s' command
-+sets cells and has already been described above. The `n' command displays
-+the next generation of the current object, and will wrap around from the last
-+generation back to generation 0. The `p' command displays the previous
-+generation, also wrapping around. The `w' command writes out a picture of
-+the current generation out to the specified file. The `d' command dumps
-+the state of the search out to the specified file (see below). The `N'
-+command will continue searching for the next object after an object has
-+been found. The `v' option specifies the frequency of automatic viewing.
-+The `c' command turns all unknown cells in the current generation OFF.
-+Finally, the `q' command quits the program (confirmation is required).
-+.P
-+Since it can take a very long time to find something (days or even weeks!),
-+the current state of a search can be dumped to a file and read again later.
-+You can explicitly dump the status to a file by using the `d' command.
-+After this has been done, you can use `q' to quit the program. Then later,
-+you can use the -l command line option to continue searching.
-+.P
-+More useful and safer, however, is the autodump feature of the program.
-+Using the -d command line option causes a dump status file to be automatically
-+written after every so many search iterations. Thus every so often the
-+specified file will contain the latest status of the search. Then if your
-+machine crashes, you will not have lost days of work. The -d option takes a
-+numeric operand, which is how many thousand searches to perform between dumps.
-+The option also takes a filename as an argument, and if it isn't given,
-+defaults to "lifesrc.dmp". As an example, the option "-d100 foo" results
-+in automatically dumping status about every 10 minutes to the file "foo".
-+.P
-+To load the dumped state that has been saved to a file, use the -l or -ln
-+command line options. Since the status file contains all information about
-+the search configuration, you do not need to specify the number of rows,
-+columns, generations, translations, symmetries, or initial settings again.
-+However, if you wish autodumps, an output file, or automatic viewing, then
-+you have to specify those options again.
-+.P
-+After the state has been loaded, generation 0 is displayed and either the
-+program enters command mode if -l was used, or else the search immediately
-+continues where it left off if -ln was used. The -ln option is provided so
-+that continuing the search program within shell scripts is easy.
-+.P
-+There are two versions of the program, called lifesrc and lifesrcdumb.
-+They perform the same functions, but the user interfaces are slightly
-+different. Lifesrc uses the curses display routines to display the
-+objects prettily, whereas lifesrcdumb assumes nothing fancy and just
-+prints objects simply.
-+.P
-+As you can see, finding something requires skill, luck, and patience.
-+Since you are limiting the search by specifying a rectangle, symmetry,
-+maximum cells, and initial cells, you probably have to keep varying
-+these parameters in order to come across something.
