+# Source forces file arguments to be considered in the current directory
+# only, unless there is an absolute path starting with `/'.  I think it's
+# bad that the builtin "source" searches PATH, because PATH normally
+# contains directories with binary files that aren't useful for bash to
+# read and most people don't put "." first in their path.
+#
+# This "source" is capable of reading more than one file at a time.  Return
+# value is number of failed source attempts.

+
+# This function is not hygienic, but there's not much we can do about
+# variable name conflicts here.
