+COMMENT  = Makefile to build libe_sqlite3.so from sources in https://github.com/ericsink/cb/tree/master/sqlite3 and https://github.com/ericsink/cb/tree/master/stup
+LICENSE  = Apache 2.0
+
+# libe_sqlite3.so is the native library for linux provided by SQLitePCLRaw nuget package.
+# Since the (cross) toolchains used for creation in https://github.com/ericsink/cb provide newer libc versions, 
+# these libraries depend on GLIBC 2.28.
+# Such toolchains are used since SQLitePCLRaw 2.0.5.
+# 
+# As .NET 8 and .NET 9 do not have such restrictions and run well on DSM 7.1.1 with GLIBC 2.26
+# and on DSM 6.2.4 with GLIBC 2.20, we create libe_sqlite3.so here with the toolchains from 
+# Synology for compatibility with DSM.
