Comment 2 for bug 146743

This is interesting, since the description of the package texlive-lang-czechslovak clearly states:
Pick this if you want Czech/Slovak fonts and other packages

This package includes the following CTAN packages:
 cs -- CM fonts extension for Czech/Slovak.
 cslatex -- LaTeX support for Czech/Slovak typesetting.
 csplain -- Plain TeX support for Czech/Slovak typesetting.
 bin-cslatex -- LaTeX support for Czech/Slovak typesetting.
 bin-csplain -- Plain TeX support for Czech/Slovak typesetting.
 bin-vlna -- Binaries for the Vlna program.
 hyphen-czechslovak -- Czechslovak scripts

(taken from Synaptic's description of package)

This program is actually needed on every platform you intend to typeset Czech documents on. Prepositions (and certain connectives) connected to words (e.g. "k Pavlovi") cannot be split - you cannot leave the preposition "k" at the end of one line and continue the word to which it connects (in this case "Pavlovi") on the next line - this is against Czech typographical rules.

I think that given the description of the package, the program _should_ be present, so that's why I filed it as a bug. Especially considering that after installation the manual page is present, but the program Vlna itself not.

Best regards,
