*: WIP adding man page

Clean up Makefile for the tools to be pulled in as needed by jobs like
building man pages (or linting, etc.)

Building docs in the default step. But installing the man page is
currently an exercise for the reader.

+==================================================
+
+# NAME
+gomtree - filesystem hierarcy validation tooling and format
+
+# SYNOPSIS
+**gomtree** [**-in**=*/path/to/md/file*] [**-out**=*/path/to/output*]
+
+# DESCRIPTION
+**go-md2man** converts standard markdown formatted documents into manpages. It is
+written purely in Go so as to reduce dependencies on 3rd party libs.
+
+By default, the input is stdin and the output is stdout.
+
+# EXAMPLES
+Convert the markdown file *go-md2man.1.md* into a manpage:
+```
+go-md2man < go-md2man.1.md > go-md2man.1
+```
+
+Same, but using command line arguments instead of shell redirection:
+```
+go-md2man -in=go-md2man.1.md -out=go-md2man.1
+```
