A few comments and suggestions on -grlog2html-.

1. It wouldn't take much to relax the restriction on only doing PNG
files... I think "file .* written in .* format" would do it (unless
there are any commands other than -graph export- that give this
message..., maybe there are, I can't think right now).

2. I believe Stata always includes the file extension in its message if
there is one, so the code to add .png if it is missing will not do
anything helpful.

3. Why do you remove the path, when there is one? If I put the image
into a different folder, then I would want the html to point there.

4. The code will fail for multiple word file names, e.g. if I export "my
graph.png", it will add a link to "my.png". For paths with spaces in,
you will end up with the last word before the space followed by .png. My
best 5 minute go at sorting this would be to code:

local gr_name = substr(`"`line'"', 7, index(`"`line'"',"written in ")-7)

This should only fail if the file name (or path) contains "written in "
(or is ridiculously long).

5. One final suggestion- It would be quite straight forward to add an
extra option to be put verbatim into the <img> tag.

David
