The script was originally created by jav so the big thanks must go to him I've just put all the instructions together in one place and hopefully in a format that is easy for others to follow.

To add other POI's just follow the instructions again only this time put the new category in an appropriate group eg. if you wanted to add stores then it would make sense to add them to the 10005 group seeing as this is "Pub. places, businesses, shops"

However make sure you check your asc input files because the perl script is expecting an input file with 3 items of data only

Longitude,Latitude,Name

and some poi files have additional columns eg. I have an Underground Station one which has 4

Longitude,Latitude,Name,Details

so would need to get rid of this 4th column of data.

You also need to ensure the 3rd column, the Name data is enclosed in "" so each line in the asc file looks like

-0.21097,51.45882,"UdGr East Putney"

If you do have a 4th column one solution is to put your "" around both the 3rd and 4th column like I have done here

-4.258263,55.852014,"UdGr Bridge Street Subway,67 Eglinton Street, Glasgow, G5 9NR"
-4.252937,55.862411,"UdGr Buchanan Street Subway,174 Buchanan Street, Glasgow, G1 2LW"
-4.29452,55.852368,"UdGr Cessnock Subway,1 Cessnock Street, Glasgow, G51 1AS"

which effectively results in just the one column which the script is happy with.

As long as your input files are of this format

Longitude,Latitude,Name
n.nnnnn,n.nnnnn,"aaaaaaaa"

you should be ok.
