### @usage: DOCS()
###
### Documentation project multimodule.
###
### When built directly, via RECURSE, DEPENDS or BUNDLE the output artifact is docs.tar.gz with statically generated site.
### When PEERDIRed from other DOCS() module behaves like a UNION (supplying own content and dependencies to build target).
### Peerdirs from modules other than DOCS are not accepted.
### Most usual macros are not accepted, only used with the macros DOCS_DIR(), DOCS_CONFIG(), DOCS_VARS().
###
### @see: [DOCS_DIR()](#macro_DOCS_DIR), [DOCS_CONFIG()](#macro_DOCS_CONFIG), [DOCS_VARS()](#macro_DOCS_VARS).
