The try.sh script has improved the judges' suggested commands in that it does not assume a certain number of columns. Instead it determines the number of columns and uses that value. It warnings (before starting) that if it's <81 it might not show up well. It also warns that it should be white text on a black background. The Makefile copies the program to the name the author gave the program. The README.md file has been format/typo checked and fixed. This completes the review of 2000/bmeyer and it should also complete the review of 2000 the 2000/README.md file notwithstanding (this goes for all the YYYY/README.md files).
