+Autostyle
+Automatically apply a given style when an exif tag is present in the file. This tagged is checked with exiftool, in order to be able to match very exotic tags.
+I wrote this initially to be able to apply a style to compensate for Auto-DR from my Fujifilm camera
+
+AUTHOR
+Marc Cousin (cousinmarc@gmail.com)
+
+INSTALATION
+* copy this file in $CONFIGDIR/lua/ where CONFIGDIR
+is your darktable configuration directory
+* add the following line in the file $CONFIGDIR/luarc
+  require "autostyle"
+
+USAGE
+* set the exif configuration string in your lua configuration
+  mine, for instance, is AutoDynamicRange=200%=>DR200"
+  meaning that I automatically want to apply my DR200 style on all
+  images where exiftool returns '200%' for the AutoDynamicRange tag
+* if you want to be able to apply it manually to already imported
+  images, define a shortcut (lua shortcuts). As I couldn't find an event for
+  when a development is removed, so the autostyle won't be applied again, 
+  this shortcut is also helpful then
+* import your images, or use the shortcut on your already imported images
+* To determine which tag you want, list all tags with exiftool:
+  exiftool -j XE021351.RAF, and find the one you want to use
+  you can check it with 
+  > exiftool -AutoDynamicRange XE021351.RAF
+  Auto Dynamic Range              : 200%
