for each module we want a module definition file, module.cfg
[module]
name = pkg1
version = 0.1.0
allow_unsafe = true
plugin_for = mainpkg1:plugin_v1
internal_for = friendpkg1
minimum_int_bits = 32
minimum_size_bits = 32
[metadata]
website = https://xxx
author = yyy
[updates]
dl_url = https://xxx
dl_url_format = .tar.zst (or MIME type?)
dl_url_signkey = base64:MID343SDF2f4sdff23Sf42ds3423...sdFDf=
dl_check_url = https://xxx
dl_check_pattern = /latest version: (.*)/\1/
dl_check_signkey = key1
repo_url = https://xxxx/xxx.git
repo_type = git
repo_release_pattern = /v(.*)/
repo_release_replace = /-/./
repo_release_signkey = key1
[keys]
key1 = base64:MID343SDF2f4sdff23Sf42ds3423...sdFDf=
[dependencies]
pkg1 = least:0.5.3
pkg2
meta_pkg1
[build_dependencies]
pkg3 = least:1.2.0
[run_dependencies]

pkg5 = optional
[broken_dependencies]
pkg2 = range:0.1.2.1:0.1.2.5,0.1.3.0
there should be this standard file/directory structure.
only the module.cfg file, and at least one of (asm, data, dev-doc, doc, src, test), are required.
asm/ (if allow_unsafe is true)
asm/x86_64-linux-gnu/*.cfg (assembler options, e.g. syntax. default.cfg for defaults)
asm/x86_64-linux-gnu/*.asm (for example)
data/
dev-doc/
doc/
plugin-interface/
src/
test/data/
test/unit/**.sul
test/system/**.sul
test/exec/**.cfg
README
module.cfg
interface.sul (for libraries)
building should store files in a local cache directory (perhaps tmpfs, or rarely synced-to-disk partition)
modules are installed into these directories:
/sys/exe/arch/
/sys/lib/arch/
/sys/lib/arch/other_pkgname/pluginapiname/
/sys/data/res/pkgname/
/sys/data/doc/pkgname/
/sys/data/src/dev-doc/pkgname/
/sys/data/src/dev-interface/
/sys/data/src/dev-plugin/pkgname/
builtin-software is installed in a special parition, which is updated as a disk image (with reproducible bindiff/"fsdiff" commands)
with A/B partitions
on top of this, the other directories are overlaid
additionally, there are these runtime directories
/sys/cache/
/sys/cfg/pkgname/
/user/username/
by default, an app can see these directories
/sys/lib/arch/pkgname/pluginapiname/ (as /app/plugins/)
/sys/data/res/pkgname/ (as /app/res/)
/sys/data/doc/pkgname/ (as /app/doc/)
