LibreOffice in your browser — notices for the Office to PDF converter
=====================================================================

YourDevice's Word, PowerPoint and Excel to PDF tools run LibreOffice 24.8.8,
compiled to WebAssembly, in your browser. These files are served from
/models/libreoffice/lo-24.8.8-yd1/:

  soffice.js     Emscripten loader (MPL-2.0) — modified, see below
  soffice.wasm   LibreOffice 24.8.8 and the libraries linked into it
  soffice.data   LibreOffice's configuration, filters and bundled fonts

The WebAssembly build
---------------------
The three files come from the npm package @matbee/libreoffice-converter 2.7.2
(MPL-2.0), https://github.com/matbeedotcom/libreoffice-document-converter,
which publishes the build scripts used to compile them.

Our modification
----------------
One change to soffice.js: the Emscripten thread pool starts 16 workers
instead of 4. The patch is pool-size.patch, beside this file; nothing else in
the three files is changed. soffice.wasm and soffice.data are byte-identical to
the published package (sha256 below).
