xhld ? ...
It's my mistake.

But it's almost the same.

How to create the 101th instance of xhld ...

copy:
sql/mysql.sql -> sql/mysql101.sql
templates/xhld_index.html -> templates/xhld101_index.html
templates/xhld_block.html -> templates/xhld101_block.html
templates/xhld_feed.html -> templates/xhld101_feed.html
templates/blocks/xhld_block_rss.html -> templates/blocks/xhld101_block_nss.html
templates/blocks/xhld_block_mixed.html -> templates/blocks/xhld101_block_mixed.html

edit:
sql/mysql101.sql

Of course, the number of "101" is just a sample.
Normally, you'll make xhld4.
