+# App registry -- apps eligible for theme switching
+#
+# Each app must be register under the "app" directive, i.e., as "[app.<app-name>]"
+#
+# Option details:
+# - external_theme: if False (default), indicates an app of type 1 as per the README. That
+#   is, an external theme file cannot be used, and theme switching will involve switch the
+#   canonical config setting. If True, the app's theme can be set through an external theme
+#   file.
+# - support_os: OSes that support theme switching according to the implemented paths.
+#   Accepts a list of `uname -s` strings to match system.
+# - refresh_cmd: a command to run for live refreshing the application's color scheme after
+#   it's been set for running instances.
+#
+# Default example 
+# [app.default]
+# external_theme = False
+# config_dir     = '~/.config/default/'
+# config_file    = 'default.conf'
+# refresh_cmd    = 'app reload-config'
