I cleaned those out as well (the echo -n "bug" was in there ;) and moved
them into the scripts dir. I also added a --list option to show already
installed languages.
This whole moving and renaming totally confused CVS and my checked out
copy got completely fried last night. When you apply the source patch,
please make sure that all the directories src/bin/{create|destroy}* as
well as vacuumdb, cleardbdir are gone and that all the scripts (7) are
in
scripts/.
Meanwhile I am still puzzled about what happened with the docs patch.
Because I don't know what you got now, the second attachment contains
the
