applications of λδ version 2.
In particular it contains the components below.
- MLTT1.
Martin-Löf's Type Theory with one universe
using λδ as theory of expressions.
- Functional.
The validation algorithm for λδ as implemented in
Helena 0.8.

Logical Structure of the Specification
The source files are grouped in planes and components
according to the following table.
Each component contains its own notation file.
The notation for the relations or functions introduced in each file
is shown in parentheses (? are placeholders).

| MLTT1 |
| genv_primitive | judgement |
| functional | reduction and type machine | rtm | rtm_step ( ? ⇨ ? ) |
| unfold | lift ( ↑[?,?] ? ) | subst ( [?←?] ? ) |
Physical Structure of the Specification
The source files are grouped in directories,
one for each component.
