-All I did to compile it was add: '|| defined(linux)' to the end of line 49
-of xfish.c, and added: '#ifdef linux signal(SIGUSR1, toggle_secure); #else'
-at line 1469 followed by '#endif /* LINUX */' at line 1495.
-
-I didn't figure this out for myself either, I just looked at the port of
-xfishtank1.0 at sunsite /pub/Linux/X11/demos/xfishtank.tar.Z
-done by: Dave Black dlbb0@amdahl.com
-
-I included the source and 'stripped' binary compiled with gcc2.2.2d7 and the
-jump4.1 libs under linux-0.99 and Xfree86v1.1
-
-I've been using it for months now without any problems. Much improved over
-xfishtank1.0, there are loads of new 'way cool' fish which posess the ability
-to swim on top of gifs!!
-
-One last note, the current Makefile was generated by my Xfree86v1.1 xmkmf
-and uses a -m486 CCOPTION, I don't know if this would cause it to not work
-on other machines or not (the binary, if it doesn't work try changing it to
--m386, and recompiling) ???
-
-I'm uploading it to sunsite.unc.edu /pub/Linux/X11/Incoming

-Here is the README:

- ********************** FUN WITH FISH *********************
-
-There are lots of programs for lots of platforms to make fish swim in the
-background of your screen. This is a modification of an old one called
-xfish (also called Xaquarium), that I have added more features to.
-
-To not confuse you (or confuse you more) I will call this modified xfish
-"xfishtank". ['A rose by any other name...' and all that]
-
-
-How is this different? I started with you basic xfish, and I kept the
-bubbles (actually I re-wrote some of the bubble code, but it LOOKS the same).
-I changed the rest of the code to allow any number of multicolored fish to
-swim around. Each fish can have up to 255 colors, but on startup the program
-takes all the colors from all the fish, and squeezes them down to all fit
-into the default colormap as best it can. Any fish can be any size in
-width and height. To make them look more like they are swimming, fish are
-animated (Very simple 2 frame animation) [I got this idea from watching
-the AfterDark fish on the Mac]. Fish CANNOT swim over each other, they
-will turn around if they are about to collide. I had a version that
-had fish swiming over each other, it was WAY to slow to be something to run
-on your background while working, so I deleted it.
-
-xfishtank -help to see the command line options.
-
-
- ********************** NEW FUN WITH FISH *********************
-
-Since the original version, I have received various comments and bug fixes.
-This version I know runs on SGIs running 4.0, Sparcs running 4.1,
-Decstations running 4.1, and RS6000s running 3.1. However, there were mongo
-memory leaks in the X server distributed with the RS6000, so I had to compile
-the X11R5 server and use that.
-
-As you add more fish (especially very colorful fish) the total color use set
-becomes quite large (greater than 255). I added 2 new options to help you
-deal with this. By default xfishtank would find the total color use set
-for all the fish you requested, and then start allocating out of the default
-colormap until it filled up, it would then match the rest of the colors to
-whatever colors it could get. This first come first serve color allocation
-can give really bad results for large color sets. I added the -m option
-to allow you to specify that the program should cut the color use set down
-to the number you specify with the -m option before starting to allocate
-out of the default colormap. The algorithm used by -m is considerably better
-than first come first serve. Also, having xfishtank use ALL the available
-cells in the default colormap can be bad. The -C options lets you limit how
-many cells xfishtank will take out of the default colormap.
-In the first come first serve senario colors are allocated for the fish,
-in the order of appearance in the FishList file, and then from the backgound
-picture if one exists.
-
-Finally, due to popular demand, I put back in my clipmask code. By setting
-the -d option (for Do clipping), xfishtank will swim its fish over whatever
-you already have on your root window. WARNING: This will slow down your
-machine! The reason I took this code out originally was it slowed my
-machine down too much for me to comfortably work. But if you think you have
-a really spiffy fast workstation, go ahead and give it a try.
-
-If you use the -d option and notice some flicker (which I expect you will),
-this is because xfishtank is just doing an XClearArea, and letting the root
-redraw its background. If you know what you want your background picture to
-be, use -p <image_file> instead of -d. The image_file needs to be a gif
-image. Since xfishtank now knows what your background is, xfishtank with
-the -p option should have much less flicker. However, it suffers the
-disadvantage that you can't change the background picture without restarting
-xfishtank.
-
-The intrepid explorer of the source code will notice that there are some
-options not described in xfishtank -help. In particular -o -and -D. These
-options aren't described because they were stuff I was fussing with and couldn't
-get to work. I left them in on this release so that if someone else wanted
-to try and get them to work, they could see what I had already tried. The -o
-option lets fish try and swim on top of each other. It looks ugly no matter
-how I do it, if you can fix it, great. -D is a special option that is only
-active if you have also specified -d and -p. Normally you never want to specify
-both -d and -p because it doesn't make the animation any better, and it
-slightly messes up fish to bubble intersections. However, if you specify
--d -D -o -p you will get as close as I could get to proper fish intersections.
-And when you see how crumby these are, and how slow it makes your machine
-you will know why I gave up.
-
-Ok, I'll fess up, I'm lying, I did actually get good fish to fish intersections
-but only by writing a completely different version of xfishtank that has
-each fish be a shaped override-redirect window, that moves itself, and changes
-its shape-mask to animate. This looks REALLY COOL, but grinds any and all
-X servers to a complete standstill.
-

- ********************** NEW FISH PICTURES *********************
-
-This release contains a grand total of 29 fish! These fish were carefully
-created through lots of hard work, and the help of many many people who
-sent me pictures of fish, non-copyrighted gifs of fish, and allowed me to
-borrow their scanners. I'm not going to try and name them all here, there
-are lots of you, and I'm afraid I may miss someone. You all know who you are,
-and you have my heartfelt thanks, I couldn't have done this without you.
-
-
- ********************** TROUBLE WITH FISH *********************
-
-There is a scarcity of good fish pictures in the world, and they are all
-protected by lawyers. Here is the solution I propose.
-
-Any of you with talent can edit up any pictures you want, somehow get them
-into GIF format, and import them into your xfishtank. The program
-"giftofish" that I am supplying here takes as input any 2 GIF files,
-and creates a xfishtank header file for that fish. The 2 files must have
-the same width and height, and must both have the same background color.
-The pictures are assumed to be the two frames of an animated fish swiming right.
-Put this new header file into your fishmaps directory, edit the FishList
-file to add the prefix of that header file, and increment the total fishcount
-on the first line of that file. Now recompile xfishtank, and your new fish
-will be used. Also, the program fishtogif will extract the two gifs from
-any fish header file so you can touch up what you already have.
-
-Other fish sources:
- The AfterDark fish on the Mac are beautiful. If you
-have already shelled out the money to Berkely Systems Software to buy those
-fish, and you also want to see them on your UNIX box, here is what you do.
-If you can transfer the Mac fish files to UNIX, run the "gofish" program
-supplied here, it will write out the fish into two intermediate files.
-The files will look strange, they are my own format, just feed them to the
-giftofish program (which understands that format), and it will create a
-fish header file for you.
- OpenWindows 3.0 comes with some fish pictures. If you have purchased
-Openwindows, and want to use those pictures, the program "rasttofish"
-supplied here will read one of their sun raster fish pictures, and produce
-a xfishtank header file for it. Note, the Openwindows fish are only one
-frame, so the won't be animated.
- There is apparently a PC Windows program with some swimming fish.
-The individual fish are stored in .fsh files. The program pcfshtofish
-will turn one of these .fsh files into an xfishtank header file.
-

- ********************** THANKS *********************
-
-A really big thanks to well over 100 wonderful people who after downloading
-the last version of xfishtank took the time to send me such pleasant,
-complimentary, and supportive e-mail. This version was never planned, but
-all of you have made me feel better about writing this code than anything
-that any employer has ever paid me for.
-
-
-As usual, mail any problems, questions, complaints, reccommendations, and
-cookies to me.
