/* This loader opens a directory as a library. In the long run, the idea is
* that one folder will have all of objects files, all of the related
* *-help.pd files, a file with meta data for the help system, etc. Then to
* install the lib, it would just be dropped into extra, or the path anywhere.
*
* Ultimately, the meta file will be read for meta data, specifically for
* the auto-generated Help system, but for other things too. Right now,
* its just used as a marker that a directory is meant to be a library.
* Plus its much easier to implement it this way, I can use
* open_via_path() instead of writing a new function. The grand plan is
* to have one directory hold the objects, help files, manuals,
* etc. making it a self-contained library. <hans(a)at.or.at>

--- NEW FILE: TODO ---
- implement [classpath] which adds a path to the global path, like what
[declare -stdpath] does. The idea is that the global path serves as a
Java-style classpath. and the local path serves as the namespace.
- inlet accepts bang to output classpath on outlet
- inlet accepts messages to add items to the classpath
- follows same interface as [textfile], [qlist]
- implement [import] which adds the libdir path to the canvas path, similar
[declare -lib] does, except that it only looks in the global path (aka
classpath)
- inlet accepts bang to output canvas path on outlet
- inlet accepts messages to add items to the canvas path
- follows same interface as [textfile], [qlist]
- make [libdir] load libdirs when they are called with [import] and [declare
-lib] and [declare -stdlib].
- [libdir] loader should only add the libdir to the helppath, not the
additional doc/5.reference path to the helppath. The idea is that libdirs
are self-contained.
