Packaging of a standalone program (Digestif)

Hi Augusto,

I've also written a Lua project <> and
it works in TeX Live.  I hope the following helps.

The path finding scheme in LuaTeX with TDS is different from standard Lua.
Besides the file name issue mentioned by Karl, the code related to path finding
may also need adaption for TDS. In general, `kpse.set_program_name("luatex")`
is required in the main executable script to load Lua modules from the TDS (see
also section 4.2.2 in the LuaTeX manual).  It replaces `package.searchers[2]`
with the kpse loader which, unlike in standard Lua, looks for Lua modules by
only their basenames.  This means
`TEXMF/scripts/digestif/digestif-langserver.lua` can be loaded via
`require("digestif-langserver")` (provided it's prepended with`digestif-`).
The `.tags` files can be put in `TEXMF/tex/generic/digestif/`and they are
accessed via `kpse.find_file("digestif-primitives.tags")` .

BTW, you can install the files to `kpsewhich -var-value=TEXMFHOME` to test the
TDS structure.
