# DocFX uses short names for all <see> links which is inconvenient for us
# because we have multiple types with the same name in different namespaces
# ("Object" can be "Efl.Object" or "Efl.Canvas.Object").
# MarkDown files can add "?displayProperty=fullName" to crefs to show them
# fully-qualified, but this is stripped out from triple-slash comments in C#
# source files.
#
# This script adds the displayProperty suffix to all cref links from the
# metadata yml files (by that time links have been turned into <xref href="">
# tags).
