• register/unregister (incomplete implementation from visual studio RGS sample file)
• integrate WIDL.exe (wine version of MIDL)
• finish TTypedComObject
• create TAutoObject
• implement tlbimp.exe
• port to linux as NPAPI wrapper (just partially kidding ;) as base you can us my updated NPAPI scripting code (https://www.mozdev.org/bugs/show_bug.cgi?id=8708) [^] - already working with FPC (similar entry point functions as in COM) :)

• integrate MIDL.exe (wine old version of MIDL has an incorrect output format :( )
• try building latest WIDL -> report bugs to wine
• create TAutoObject
• finish tlbimp.exe (bug 0014802)
