Perl scripts event handlers must ALWAYS return value. Lua scripts
allow you don't return any value in some handlers like Main/Unload/VH_OnTimer
etc. But your perl script should ALWAYS return 1 in Main/Unload/VH_OnTimer.

You may use vh::SQLQuery/Fetch/Free or use DBI interface (vh::VHDBConnect)

Your hub_security will show you runtime errors (e.g. divide by zero). Compile
time errors will be logged in $VERLIHUB_CFG/err file only.

If you receive many errors '&vh::constant not defined' just type command:

  perl -Mvh

then submit bug with output of this command.

vh::GetNickList/vh::GetOPList/vh::GetBotList have equivalent functions
vh::GetNickListArray/vh::GetOPListArray/vh::GetBotListArray that returns
array of nicks.
