Package texlive-vlna

Adds tilde after each non-syllabic preposition

http://tug.org/texlive/

There exists a special Czech and Slovak typographical rule:
you cannot leave the non-syllabic preposition on the end of one
line and continue writting text on next line. For example, you
cannot write down the text "v lese" (in a forest) like
"v<new-line>lese". The program vlna adds the asciitilde between
such preposition and the next word and removes the space(s) in
this place.  It means, the program converts "v lese" to
"v~lese". You can use this program as a preporcessor before
TeXing. Moreower, you can set another sequence to store instead
asciitilte (see the -x option).
