+Contains the Network Security Services (NSS) libraries from Mozilla
+
+== Fips 140 and signed libraries ==
+
+Fips 140 mode is not supported. That is, the *.chk files containing the
+checksums for the cryptographic module are not delivered into instdir and will
+not be part of the OOo installation sets.
+
+Signing has been turned off because
+- we change the rpath (install names) after signing which breaks the signatures
+(Mac)
+- sqlite conflicts with the system sqlite when signing which breaks the build
+

+
+== libsqlite3 ==
+
+With all supported macOS SDK we use
+NSS_USE_SYSTEM_SQLITE=1
+to build using the system sqlite.
+
+== system NSS on Linux ==
+
+Note that different Linux distributions use different SONAMEs for the
+NSS libraries, so it is not possible to use --with-system-nss and build
+a portable generic LO installation set, despite NSS upstream apparently
+maintaining ABI compatibility.
