# Caution: do not add files or directories here using wildcards. This

# will result in problems later if a new file matching the wildcard is
|
|
# added to the source tree -- nothing will cause configure to be rerun

# tests might fail. Prefer to keep the relevant files in their own

# UNLINK is used to remove symlinks from older development versions
|
|
# that might get into the way when doing "git update" without doing
