**
**  --max-cpu SEC    Maximum number of seconds of CPU time allowed per
**                   HTTP connection.  Default 30 (build option:
**                   -DMAX_CPU=integer). 0 means no limit.
**
**  --debug BOOLEAN  Disables input timeouts.  This is useful for debugging
**                   when inputs are being typed in manually.
**
**  --enable-sab     Add new lines to the HTTP reply header that are
**                   prerequisites for SharedArrayBuffer.  These are the lines:
**                     Cross-Origin-Embedder-Policy: require-corp
**                     Cross-Origin-Opener-Policy: same-origin
**        
**
** Additional command-line options available when compiling with ENABLE_TLS:
**
**  --cert FILE      The TLS certificate, the "fullchain.pem" file
**
**  --pkey FILE      The TLS private key, the "privkey.pem" file.  May be
**                   omitted if the --cert file is the concatenation of
