     (library? obj)
 
+Predicate - return `#t` if the given `obj` a `define-library` S-expression or `#f` otherwise.
+
+# library-exists?
+
+    (library-exists? import-set)
+    (library-exists? import-set file-extension)
+
+Determine if a library exists on the file system for the given import set.
+
+Checks for the default file extension of `.sld` unless `file-extension` is provided.
+
 # lib:list->import-set
 
+    (lib:list->import-set lis)
+
+Convert a raw list to an import set. For example, a list might be `(srfi 18)` containing the number `18`. An import set contains only symbols or sub-lists. Any numbers are converted to the corresponding symbol.
+
+This is also a convenient time to do any name conversions from an alias to the actual library, so any such conversion will also be performed.
+
 # lib:name
 
+    (lib:name ast)
+
+Return the library name as an import set. For example `(scheme base)`.
+
 # lib:name->string
 
+    (lib:name->string name)
+
+Convert name (as list of symbols) to a mangled string.
+
 # lib:name->symbol
 
+    (lib:name->symbol name)
+
+Convert library name to a unique symbol.
+
+# lib:name->unique-string
+
+    (lib:name->unique-string name)
+
+Convert name (as list of symbols) to a mangled string guaranteed to be unique.
+
 # lib:result
 
+    (lib:result result)
+    
+Helper function that returns `result` unless `result` is `#f` in which case the empty list is returned as a default value.
+
 # lib:exports
 
+    (lib:exports ast)
+
+Return the library's exports.
+
 # lib:rename-exports
 
+   (lib:rename-exports ast)
+
+Return the library's exports that are renamed.
+
 # lib:imports
 
+    (lib:imports ast)
+
+Return the library's imports.
+
 # lib:body
 
+    (lib:body ast)
+
+Return the given library's body. IE, the contents of `begin`.
+
 # lib:includes
 
+    (lib:includes ast)
+
+Retun the library's include directives.
+
 # lib:include-c-headers
 
+    (lib:include-c-headers ast)
+
+Return the library's `include-c-headers` directives.
+
 # lib:import->filename
 
+    (lib:import->filename import)
+    (lib:import->filename import extension)
+    (lib:import->filename import extension append-path)
+    (lib:import->filename import extension append-path prepend-path)
+
+Resolve library filename given an import `import`. 
+
+Options:
+
+- `extension`, assumes ".sld" file extension if one is not specified.
+- `append-path`, list of strings
+- `prepend-path`, list of strings
+
 # lib:import->metalist
 
+    (lib:import->metalist import append-dirs prepend-dirs)
+
+Given an import set `import` find the associated `.meta` file, if it exists, and return its contents. An empty list is returned if a file cannot be found.
+
 # lib:import->path
 
+    (lib:import->path import append-dirs prepend-dirs include)
+
+Get path to directory that contains the library.
+
 # lib:read-imports
 
+    (lib:read-imports import append-dirs prepend-dirs expander)
+
+Given a single import from an import-set, open the corresponding library file and retrieve the library's import-set.
+
 # lib:import->export-list
 
-# lib:resolve-imports
+    (lib:import->export-list import append-dirs prepend-dirs expander)
+
+Read export list for a given import.
 
 # lib:resolve-meta
 
+    (lib:resolve-meta imports append-dirs prepend-dirs)
+
+Return contents of all `.meta` files for the given import sets `imports`.
+
 # lib:get-all
 
+    (lib:get-all ast tag)
+
+Get all instances of given tagged list from a library definition, and collect the contents of them into a single list.
+
 # lib:get-all-import-deps
 
+    (lib:get-all-import-deps imports append-dirs prepend-dirs expander)
+
+Given an import set, get all dependant import names that are required
+The list of deps is intended to be returned in order, such that the
+libraries can be initialized properly in sequence.
+
 # lib:get-dep-list
 
+    (lib:get-dep-list imports)
+
+Given a list of alists `(library-name . imports)`, resolve all of the dependencies and return an ordered list of library names such that each library is encounted after the libraries it imports (IE, it's dependencies).
+
 # lib:imports->idb
 
+    (lib:imports->idb imports append-dirs prepend-dirs expander)
+
+Take a list of imports and create a "database" from them
+consisting of maps between each exported identifier and the
+library that imports that identifier. 
+
 # lib:idb:ids
 
+    (lib:idb:ids db)
+
+Take an idb "database" `db` and create a list of identifiers that are imported. EG: `((call/cc . (scheme base)))` ==> `(call/cc)`
