I saw it use Xailer but the source code seem more easy than mod_harbour
seehttps://samples.nefele.dev/ejemplo thi s sample
the nefele author make the differences from Mod_harbour and nefele
https://nefele.dev/blog/programacion-web-con-mod-harbour-y-nefele/
inserting pieces of programmation on Mod_harbour and nefele
in my opinion the mod_harbour language must be easier and easier to assimilate as just like the fwh language
for a sample there is a class calendar as our Daniel Tcalex
