Narrowly-POSIX complient UNIX tools

This project aims to be as POSIX complient as possible.
There are no extra options other than described by the POSIX standard,
but there are a few extra programs (like init).

Notes

Finding sources with missing copyright:
diff <(grep -rn '^//\s*GNU General Public License' src | cut -d':' -f1) <(find src -type f)
Code I used to make the links:
awk -F'|' 'NR>=34&&NR<=74{printf "|%s|%s|%s|%s|\n", $2, $2, $3, $4, $5 }' README.md| sed 's/\s+/ /; s//\s*///; s/\s*././; s/[\s*/ [/; s/\s*]/]/; s/)/) /'
