.BThis command will start the Roxen WebServerB.. 
 
The environment variable .BROXEN_ARGSB. can be used to specify 
the default arguments. 
 
   .BArguments:B. 
 
      .B--versionB.:                  Output version information. 
 
      .B--help -?B.:                  This information. 
 
      .B--remove-dumpedB.:            Remove all dumped code, thus forcing 
                                  a recompile. 
 
      .B--verbose -vB.:               Enable more verbose messages. 
 
      .B--quiet -qB.:                 Disable most of the messages. 
 
      .B--log-dir=DIRB.:              Set the log directory. Defaults to .B../logsB.. 
 
      .B--config-dir=DIRB.:           Use an alternate configuration directory. 
                                  Defaults to .B../configurationsB.. 
 
      .B--debug-log=FILEB.:           Use an alternate debuglog file. 
                                  Defaults to .B../logs/debug/B.configdirname.B.1B.. 
 
      .B--pid-file=FILEB.:            Store the roxen and startscript pids in this 
                                  file. Defaults to .B../configurations/_roxen_pidB.. 
 
      .B--silent-startB.:             Inhibits output to stdout. If used, 
                                  this argument must be the first one. 
 
      .B--without-ram-cacheB.:        Do not use an in-RAM cache to speed 
                                  things up. Saves RAM at the cost of speed. 
 
      .B--without-ram-cache-statB.:   Disable the stat that is usualy done 
                                  for files in the ram cache to ensure that 
                                  they are not changed before they are sent. 
                                  Improves performance at the cost of constant 
                                  aggravation if the site is edited. Useful for 
                                  truly static sites. 
 
      .B--with-threadsB.:             If threads are available, use them. 
 
      .B--without-threadsB.:          Even if threads are enabled by default, 
                                  disable them. 
 
      .B--with-profileB.:             Store runtime profiling information on 
                                  a directory basis. This information is 
                                  not saved on permanent storage, it is only 
                                  available until the next server restart 
                                  This will enable a new 'action' in the 
                                  administration interface 
 
      .B--with-file-profileB.:        Like .B--with-profileB., but save information 
                                  for each and every file. 
 
      .B--self-testB.:                Runs a testsuite. 
      .B--self-test-verboseB.:        Runs a testsuite, report all tests. 
      .B--self-test-quietB.:          Runs a testsuite, only report errors. 
 
      .B--onceB.:                     Run the server only once, in the foreground. 
                                  This is very useful when debugging. 
 
      .B--gdbB.:                      Run the server in gdb. Implies .B--onceB.. 
 
      .B--programB.:                  Start a different program with the roxen 
                                  Pike. As an example, 
                                  .B./start --program bin/install.pikeB. will 
                                  start the installation program normally 
                                  started with .B./installB. 
 
      .B--with-debugB.:               Enable debug 
 
      .B--without-debugB.:            Disable all debug 
 
      .B--with-fd-debugB.:            Enable FD debug. 
 
      .B--with-dump-debugB.:          Enable dump debug. 
 
      .B--trussB.:                    (Solaris only). Run the server under 
                                  truss, shows .BallB. system calls. This is 
                                  extremely noisy, and is not intented for 
                                  anything but debug. 
 
      .B--truss-cB.:                  (Solaris only). Run the server under 
                                  truss -c, shows times for all system calls 
                                  on exit. This is not intented for anything 
                                  but debug. Slows the server down. 
 
  .BArguments passed to pike:B. 
 
       .B-DDEFINEB.:                  Define the symbol .BDEFINEB.. 
 
       .B-d<level>B.:                 Set the runtime Pike debug to level. 
                                  This only works if Pike is compiled 
                                  with debug (i.e. with --rtl-debug to 
                                  configure). 
 
       .B-rtB.:                       Enable runtime typechecking. 
                                  Things will run more slowly, but it is very 
                                  useful while developing code. 
 
                                  Enabled when starting roxen with --debug 
 
       .B-rTB.:                       Enable strict types. 
                                  Same as adding #pragma strict-types 
                                to all files. 
 
                                  This enables more strict 
                                  type-checking, things that are 
                                  normally permitted (such as calling 
                                  a mixed value, or assigning a typed 
                                  object variable with an untyped 
                                  object) will generate warnings. 
 
                                  Useful for module and roxen core 
                                  developers, but not so useful for 
                                  the occasional pike-script-writer. 
 
                                  Enabled when starting roxen with --debug 
 
       .B-s<size>B.:                  Set the stack size. 
 
       .B-M<path>B.:                  Add the path to the Pike module path. 
 
       .B-I<path>B.:                  Add the path to the Pike include path. 
 
       .B-P<path>B.:                  Add the path to the Pike program path. 
 
       .B-dtB.:                       Turn off tail recursion optimization. 
 
       .B-tB.:                        Turn on Pike level tracing. 
 
       .B-t<level>B.:                 Turn on more Pike tracing. This only 
                                  works if Pike is compiled with debug 
                                  (i.e. with --rtl-debug to configure). 
 
       .B-a<level>B.:                 Turn on Pike assembler debug. This only 
                                  works if Pike is compiled with debug 
                                  (i.e. with --rtl-debug to configure). 
 
       .B-wB.:                        Turn on Pike warnings. 
 
  .BEnvironment variables:B. 
 
     .BLANGB.:                        Used to determine the default locale 
                                  in the administration interface and logs. 
     .BROXEN_CONFIGDIRB.:             Same as .B--config-dir=... B. 
     .BROXEN_PID_FILEB.:              Same as .B--pid-file=... B. 
     .BROXEN_LANGB.:                  The default language for all language 
                                  related tags. Defaults to 'en' for english.
