qdsort -- Quick and dirty replacement for sort.

The purpose of this filter is to provide semi-intelligent sorting of
text files using the Latin-1 character set.  None of the switches of
the Unix sort program are supported.

Requires libdstr, available from https://flaterco.com/util/index.html.

g++ -Wall -Wextra -pedantic -O2 -s -o qdsort qdsort.cc -ldstr

Usage:  qdsort < input.txt > output.txt
