Changes in version 1.28a:
+* the input and the output files has automatically a similar extension.
+
* Russian translation added.
* NLS support updated; should hopefully be less troublesome.
* Added `-S' and `--skeleton'.
+* `%raw', `-r', `--raw' is disabled.
+
* Special characters are escaped when output. This solves the problems
of the #line lines with path names including backslashes.
