We add an initial "_title_" and "_abstract_" to all entry `.entry.json` files. The `bin/csv2entry.sh` tool reads the `summary.csv` file and loads the "_title_" and "_abstract_" to entry `.entry.json` files. Changed `bin/csv2entry.sh` VERSION from "1.3 2024-09-23" to "1.4 2024-09-27". Perform `make csv2entry` to perform the above and test under macOS. The `bin/cvt-submission.sh` tool adds "_title_" and "_abstract_" to the .entry.json based on the `.info.json` file. Changed `bin/cvt-submission.sh` VERSION from "1.2 2024-09-23" to "1.3 2024-09-27". The `bin/entry2csv.sh` tool forms the `summary.csv` file based on the "_title_" and "_abstract_" fields found in .entry.json files. Changed `bin/entry2csv.sh` VERSION from "1.3 2024-09-23" to "1.4 2024-09-27". Perform `make entry2csv` to perform the above and test under macOS. Added `-H` and `header=with-header-3` to the `bin/md2html.cfg` for the configuration entry for `[12][0-9][0-9][0-9]/*/README.md`. Changed `bin/md2html.sh` VERSION from "1.6 2024-08-17" to "1.7 2024-09-27". All entry `index.html` files now list the "_abstract_" in a new `<h3>abstract</h3>` header. Changed `bin/subst.entry-index.sh` VERSION from "1.6 2024-09-23" to "1.7 2024-09-27". Removed `summary.csv`. Added `summary.csv` and `summary.numbers` to `.gitignore`. Sorted the result with `bin/sgi.sh`. Perform `make quick_www` to perform the above and test under macOS. Perform `make www` to perform the above and test under macOS.

Judges' remarks:
The Judges believe that this is the best one line entry ever received. Compile on a UNIX system, or at least one using a C implementation that fakes it. Very few people are able to determine what this program does by visual inspection. I suggest that you stop reading this section right now and see if you are one of the few people who can.
Several points are important to understand this program:
-
What is the symbol
unixand what is its value in the program? Clearlyunixis not a function, and sinceunixis not declared to be a data type (such asint,char,struct foo,enum, ...) what mustunixbe? -
What is the value of the symbol
"have"? (hint: the value is NOT 4 characters, or'h', or a string) Consider the fact that:
char *x;
defines a pointer to a char (i.e. an address), and that the = assigns
things of compatible types. Since:
x = "have";
is legal C, what type of value is "have"?
- Note that the following expressions yield the same value:
x[3] *(x+3) *(3+x)
since addition is commutative. What can be said about this value?
3[x]
David Korn's /bin/ksh provides us with a greatly improved version of the /bin/sh. The source for v7's /bin/sh greatly inspired this contest.
