new version, it compiled finein a clean chroot (1800 seconds on a i5-46xx)

- Git isn't required for building/running it
- no need to use --workspace
- there are no plugins / other binaries provided in the sources, the
things listed with --workspace are the builtins commands and shouldn't
exist as standalone binaries
- it doesn't seem to be using C++ (but WANTLIB requires c++abi ?)
- make port-lib-depends-check is happy on amd64


if you want to experiment with it, here are a few snippets to play with on OpenBSD

open /etc/fstab | from ssv -m 1 -n
open /etc/fstab | from ssv -m 1 -n | rename device mountpoint fs options freq passno
open /etc/fstab | from ssv -m 1 -n | rename device mountpoint fs options freq passno | where fs != "ffs"
open /etc/fstab | from ssv -m 1 -n | rename device mountpoint fs options freq passno | to yaml

pkg_info | str trim | parse -r "(?<package>.*?)-(?<version>[a-zA-Z0-9\\.]*?) (?<description>.*)" | str trim description
pkg_info | str trim | parse -r "(?<package>.*?)-(?<version>[a-zA-Z0-9\\.]*?) (?<description>.*)" | str trim description | to json

ls /usr/ports/**/Makefile | sort-by modified | last 10
