Are you sure?
If You convert the package yourself to Laz .. (You don't need to become a VST Plugin developer now ..)
When creating a new "VST Plugin" project it's not saved (as designed).
Now try to save the project. With the "preset" *.ppr You get an error message.
("Project-Info-File has same name as main source file" or how to translate the error message to english ..)
Then if You manually change the ending to *.lpi in the FileSave dialog ..
... it saves the
project (it's an XML file) and then the main
unit.pas(and also the main
project file, unfortunately as *.ppr)
I saw that instead of *.dpr (like Delphi) or *.lpr it saves the "library VSTPlugin1;" as *.ppr
Please see screenshot.
