+The @sc{djgpp} @command{ln} emulates soft links for executables by
+generating a stub that in turn calls the real program.  This feature
+also works with nonexistent files like in the Unix spec. So @samp{ln -s
+src dst} will generate @file{src.exe} which will attempt to call
+@file{dst.exe}. But this feature only works for executables, therefore,
+don't rely on symbolic links on @sc{djgpp}.
