+## Disk writer logging
+
+As we have no `film' folder to log to during disk writes, the logs end up:
+
+### macOS
+
+* Disk writer backend: `/var/log/dcpomatic_disk_writer_{out,err}.log`
+* Disk writer frontend: `/Users/$USER/Library/Preferences/com.dcpomatic/2/2.16/disk.log`
+
+### Windows
+
+* Disk writer backend: `c:\Users\$USER\AppData\Local\dcpomatic\2.16.0\disk_writer.log`
+* Disk writer frontend: `c:\Users\$USER\AppData\Local\dcpomatic\2.16.0\disk.log`
+
+### Linux
+
+* Disk writer backend: `/home/$USER/.config/dcpomatic/2.16.0/disk_writer.log`
+* Disk writer frontend: `/home/$USER/.config/dcpomatic/2.16.0/disk.log`
+
+
+## Branches
+
+The main dcpomatic repo has the following branches:
+
+* `main` - the main development branch; contains 2.16.x versions
+* `v2.17.x` - development branch for v2.17.x versions; periodically rebased onto `main`
+
+The `test/data` submodule has the following branches:
+
+* `v2.16.x` - branch for use with v2.16.x versions
+* `v2.18.x` - branch for use with v2.17.x versions (as will become v2.18.x)

## Player stress testing
If you configure DCP-o-matic with `--enable-player-stress-test` you can make a script which
- ./waf pot
- cp build/src/lib/libdcpomatic.pot src/lib/po/$LANG.po
- cp build/src/wx/libdcpomatic-wx.pot src/wx/po/$LANG.po
-- cp build/src/tools/libdcpomatic-wx.pot src/tools/po/$LANG.po
+- cp build/src/tools/dcpomatic.pot src/tools/po/$LANG.po
- sed -i "s/CHARSET/UTF-8/" src/{lib,wx,tools}/po/$LANG.po
- Commit / push
- Add credit to `src/wx/about_dialog.cc` and database.
- Add to `i18n.php` on website and `update-i18n-stats` script, then run `update-i18n-stats` script.

+## Taking screenshots for the manual
+
+The manual PDF looks nice if vector screenshots are used. These can be taken as follows:
+
+- Build `gtk-vector-screenshot.git` (using meson/ninja)
+- Copy `libgtk-vector-screenshot.so` to `/usr/local/lib/gtk-3.0/modules/`
+- Run DCP-o-matic using `run/dcpomatic --screenshot`
+- Start `take-vector-screenshot`, click "Take screenshot" then click on the DCP-o-matic window.
+- Find a PDF in `/tmp/dcpomatic2.pdf`
+- Copy this to `doc/manual/raw-screenshots`
