 # Simple installer for dcraw executable, manpages, and message catalogs.
 # Dave Coffin, dcoffin a cybercom o net
+#
+# Following changes have been added for djgpp support:
+# 1) Allow for an installation prefix that can be set
+#    with a value at the command line.
+# 2) Allow for a binary extension that can be set
+#    with a value at the command line.
+# 3) No LOCALE support still, so undefine LOCALEDIR.
+#    Do not install translation of man pages.
