Description

The install.sh script referenced on:

* https://dlang.org/download.html
* https://dlang.org/dmd-freebsd.html

Uses a bash shebang, which does not work out of the box on many UNIX systems, such as FreeBSD, where bash is not installed by default.

Could we rewrite this script in pure POSIX sh, for a more portable UNIX installer?
