+  --show-limits     Display available limit names and their default values.
+  -flimit-file <file>
+                    Set limits as specified in the given file.
   -fshader-stage=<stage>
                     Treat subsequent input files as having stage <stage>.
                     Valid stages are vertex, fragment, tesscontrol, tesseval,

   -g                Generate source-level debug information.
