General Things about NewGRFs

• GRFs in alpha/beta state does change many times and should be checked before releasing new pack.
• The data from a GRF could be differ then the data from the webpage or forum or whatever, I would suggest to take the data from the GRF.
• GRFCrawler isn't always "right", TT-Forums should work if no official link available, links mostly change after update there...
• loading the GRF in OpenTTD might be a good idea for checking title, credits etc. (Title in GRF Table should be the same...)
• if there is a readme available, a link from column Details would be nice (link to www.openttdcoop.org/newgrfs/...)

Updating existing NewGRF

1. be sure, if its really a update (md5sum)
2. commit to SVN with a proper message
3. Update GRF Table (Trunk)
   1. edit title with revision number
   2. check link, if its still direct to the current revision
   3. after update, the credits might also change...
   4. write the svn revision to status

Adding new GRF

1. create a directory in the category, it belongs to. Also possible it needs an other location, because of a special dependency. Then you create a folder "a" or something like that for it, or you move it to top (1_others) or to bottom (9_last). EVERY GRF has its own directory. (svn mkdir; svn add <grf>)
2. Update GRF Table (Trunk)
   1. title with revision number
   2. link to grf
   3. don't forget the credits (you see them in the GRF itself...)
   4. write the svn revision to status

Deleting a GRF

move it to GRF Table Removed and give a reason...
