# ListPathsSafely can be used to print command parameters to a file. This is
# typically done if the command line length risk being too long for the
# OS/shell. In later make versions, the file function can be used for this
# purpose. For earlier versions, a more complex implementation is provided.
#
# The function ListPathsSafely can be called either directly or, more commonly
# from a recipe line. If called from a recipe, it will be executed in the
# evaluation phase of that recipe, which means that it will write to the file
# before any other line in the recipe has been run.
