Leafpad and Aspell

[utu]

If you don't mind using the command-line, ispell is already in Knoppix 7.6.
Give it a try.

ispell for single words, aspell for file-checking.
try aspell -c some.txt, for some.txt a text file in /home/knoppix.

I know of those command lines where Aspell is used as a stand-alone. Rather unwieldy.

In Windows, TinySpell can be used with applications which have no spell-checker such as Notepad or Wordpad.

There seems to be no equivalent for Linux. Not a big problem anyway.
