+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
+
+See also
+[https://developer.mozilla.org/en-US/docs/Mozilla/Projects/NSS/NSS_Tech_Notes/nss_tech_note6]
+
+== 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.
+
+Debian Squeeze:
+0x000000000000000e (SONAME)             Library soname: [libnss3.so.1d]
+Fedora 20:
+0x000000000000000e (SONAME)             Library soname: [libnss3.so]
