;;; db-projects.el -- Simple Directory-Based Project Management -*- lexical-binding: t -*-
;;; Commentary:
;; A project is simply a directory under `projects-main-project-directory'
;; containing either .git or .projectile. This little collection of functions
;; helps to manage these project directories and also integration them
;; consistently with the projectile package.
;; To start, first customize `projects-main-project-directory' and
;; `projects-archive-directory' as needed. Then use `projects-add-project' to
;; add new projects and `projects-archive-project' to archive them (i.e., move
;; them to `projects-archive-directory'). This package does not offer to remove
;; projects; this has to be done manually.
