+# ListPathsSafely can be used to print command parameters to a file. This is
+# typically done if the command line lenght 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.
