+#          FILE: emotty.zsh-theme
+#   DESCRIPTION: A varying emoji based theme
+#        AUTHOR: Alexis Hildebrandt (afh[at]surryhill.net)
+#       VERSION: 1.0.0
+#       DEPENDS: emotty plugin
+#    RECOMMENDS: Hasklig font
+#
+# This theme shows a different emoji for each tty at the main prompt.
+#
+# There are pre-defined different emoji sets to choose from, e.g.:
+# emoji, stellar, floral, zodiac, love (see emotty plugin).
+# 
+# To choose a different emotty set than the default (emoji)
+# % export emotty_set=nature
+#
+# For the superuser (root) this theme shows a designated indicator
+# and switches the foreground color to red
+# (see root_prompt variable, default: skull).
+# But you are using sudo (8) instead of designated a root shell, right‽
+#
+# When logged in via SSH the main prompt also shows the user- and hostname.
+#
+# The exit status of the last failed command is displayed in the window title
+# along with an indicator (see warn_glyph variable, default: collision symbol).
+# To clear it just run: $NULL, true or :
+#
+# The right prompt shows the current working directory (3 levels up) in cyan.
+#
+# When in a git repository the main prompt shows the current branch name
+# with a branch indicator in yellow
+# (see vcs_branch_glyph variable, default: Hasklig branch glyph).
+#
+# If there are modified files the prompt switches to red and shows an unstaged
+# indicator (see vcs_unstaged_glyph variable, default: circled letter M).
+#
+# If there are staged files the prompt switches to green and shows an staged
+# indicator (see vcs_staged_glyph variable, default: high voltage sign).
+#
+# In a git repository the right prompt shows the repository name in bold and
+# prepends the current working directory subpath within the repository.
+#
+# When git currently performs an action such as merge or rebase, the action is
+# displayed in red instead of the branch name and a special action indicator
+# is shown (see vcs_action_glyph variable, default: chevron).
