+This script builds NSS with gyp and ninja.

+NSS build tool options:

+    -h            display this help and exit
+    -c            clean before build
+    -g            force a rebuild of gyp (and NSPR, because why not)
+    -j <n>        run at most <n> concurrent jobs
+    -v            verbose build
+    -m32          do a 32-bit build on a 64-bit system
+    --test        ignore map files and export everything we have
+    --fuzz        enable fuzzing mode. this always enables test builds
+    --scan-build  run the build with scan-build (scan-build has to be in the path)
+                  --scan-build=/out/path sets the output path for scan-build
+    --opt|-o      do an opt build
+    --asan        do an asan build
+    --ubsan       do an ubsan build
+    --msan        do an msan build
+    --sancov      do sanitize coverage builds
+                  --sancov=func sets coverage to function level for example
+    --pprof       build with gperftool support
