filelist for processing [things to ponder]

- the plan is to have a src manifest of related .sst or .ssm files that
  can be pointed to for processing
- multilingual documents [ponder persistence for multilingual documents]
  - in the case of multilingual documents, there will be multiple
    source documents on list with different language codes, and to build
    this list, persistence is required
- inserted documents (from master .ssm or .sst) must track document root
  so inserts can be located, else not found
- consider a commandline -o --output path specifier
- steps
  - auto create filelist
    - for single source file
    - for multilinugual source files
  - process document by pointing at filelist (rather than file)
    - if necessary manually create filelist (for multilinugual source)
    - keep document root for document inserts (.ssi)
