+# Add escape sequences for italic to the TERMINFO database.
+#
+# Two ways to install:
+#
+#   1. Execute this file.
+#
+#       chmod +x terminal-italics.terminfo
+#       ./terminal-italics.terminfo
+#
+#
+#   2. Run tic yourself.
+#
+#       tic -o ~/.terminfo terminal-italics.terminfo
+#
+#
+#   Note: by writing to the home folder, we override the default themes. We
+#   could instead save this as another name, but that would report a terminal
+#   that an ssh host does not understand, which causes issues with the delete
+#   key.
