# Tests for the special target .DELETE_ON_ERROR in dependency declarations,
# which controls whether the target is deleted if a shell command fails or
# is interrupted.
#
# In compatibility mode, regular and phony targets are deleted, but precious
# targets are preserved.
#
# In parallel mode, regular targets are deleted, while phony and precious
# targets are preserved.

# See also:
# CompatDeleteTarget

# The special target .DELETE_ON_ERROR is a global setting.
# It does not apply to single targets.
# The following line is therefore misleading but does not generate any
# warning or even an error message.
