Subject: [PATCH 02/19] Add 2013/endoh3/try.sh

The script checks for SoX, padsp and otherwise ruby. It allows one to
pass in args: each one is first checked to be a readable file and if
it is it'll be processed as a file; otherwise it'll be processed as a
string. If no arg is specified it runs the program on twinkle.abc and
the strings ABC and CDEFGABc (the latter suggested by the author).

If none of the three tools noted above are installed it tells the user
to install one of them first. I was not able to test the padsp(1) one
but the invocation matches the author's remarks. /dev/dsp seems to not
be installed in modern linux systems so it would be useful to have
padsp(1) if not SoX (which is preferable in general for entries that
play sound). The ruby script wavify.rb provided by the author is the
last resort which turns the output to a WAV file.

+This program plays sound. See [FAQ 3.10 - How do I compile and use an IOCCC
+winner that requires sound?](/faq.md#faq3_10) if you do not know how to set your
+system up for this or if you want to verify that everything is oky.
+
 
 ## Try:
 
-Trying this out will depend on how your system can play sounds. The author's
-remarks include some options for different operating systems.
-
-The simplest way is to create a .wav file and have your system play that.
-
 ```sh
-echo 'CDEFGABc' | ./endoh3 | ruby wavify.rb > cde.wav
+./try.sh
+
+./try.sh ABC
+
+./try.sh test.abc yankee.abc
+
+./try.sh *.abc
 ```
 
-Observe how you will need ruby installed.
+The script will check for SoX first and next `padsp` from `PulseAudio` and
+finally if neither are found if you have `ruby(1)` installed it'll use the
+included ruby script to convert it to a WAV file for you to play.
 
-There are also some other musical samples, twinkle.abc and menuet.abc.
+If no args are passed to the script it will play [twinkle.abc](twinkle.abc) and
+the string `ABC`. Otherwise while there's a remaining arg if it's a file it will
+run the program on the file. If it's not a file it'll run it as a string.
+
+The `*.abc` files are provided as music samples.

Subject: [PATCH 03/19] Improvements to build and script of 2013/endoh4

The Makefile was modified in such a way that allows one to easily
redefine the size (in the code the S macro). For instance:

    make clobber SIZE=50,50 all

The try.sh was renamed to endoh4.sh as it's more of a wrapper to the
program rather than things to try. Also it now lets one specify more
than one file to feed to the program (in sequence).

The bugs.md was updated - added INABIAF. If the file format is invalid
it will very likely crash.

Subject: [PATCH 15/19] Fix make clobber in 2014/endoh2

Since the try script creates the files hello.c, hello, ioccc.c and ioccc
the clobber rule needs to remove those files.

The script now uses less(1) for longer output (it's possible there are
still small enough displays where it would be useful).

Subject: [PATCH 18/19] Improve 2014/morgan/try.sh

After copying prog to morgan (which was already done) it removes prog
and then uses morgan to build prog. Following this it shows that they're
identical to each other. The rest of the script it uses morgan, not
prog, and it's the same as before (what it runs) except that the use of
'ls' is no longer there as there is no need for it.

Subject: [PATCH 19/19] Fix and improve 2014/sinon scripts

The try script now runs the demo mode if perl is installed. It also now
prompts before running each script (the below noted ones) so that one
can control the pace of the output a bit more.

The glock.sh and hecate.sh scripts could only be run once successfully
because the output of run.c overwrites it (with non code). First one has
to do cp -f prog.c run.c which the scripts now do. This was not a
problem in the try script because I added that step explicitly (and is
now not needed or there).
