+# Apply any patches to original spkg sources.  Patch files must have
+# the .patch extension.
+#
+# By default the patches are applied from ../patches/ using the -p1
+# option, and it is assumed that the patches are being applied from
+# the root of the package source.
+#
+# An optional patch subdirectory may be specified with the -d flag.
+# For example `sage-apply-patches -d cygwin` applies only those
+# patches under <patch-dir>/cygwin.
+#
+# The -p<num> arg is the argument accepted by the `patch` command,
+# and overrides the default -p1
+#
+# Any additional arguments following " -- " are passed directly
+# to the `patch` command.
