• --colors=off: don't use colors; if you never want to use colors, you can set this more easily (permanently) with the run-time configuration option "colors"
• --colors=reverse: use black-on-white colors; if you always want to use colors this way, you can set this more easily (permanently) with the run-time configuration option "colors"
• --console: enter console runmode which provides a functionality similar to that of the usual, old, shell-like FTP clients; cf. Custom Connections
• --download=URL: download the content from the given URL, write it to standard output as it is received and quit when done. (Technobabble: this option causes the program to enter the download runmode.) Cf. the keyboard command "ctrl-d" for more information. Redirection of the output to a file or to another program and errors are handled as described for the "--dump" option below.
• --dump=URL: receive the document from the given URL completely, then "dump" it to standard output (layouted) and quit. (Technobabble: this option causes the program to enter the dump runmode.) Cf. the keyboard command "d". To store the output in a file, apply the shell redirection operator ">" as usual, e.g. "retawq --dump=about:retawq >ABOUT". To redirect the output to another program, apply the shell pipeline operator "|" as usual, e.g. "retawq --dump=about:retawq | wc --lines". If an error occurs, a "fatal error" message is printed to standard error (so it's redirectable with the shell operator "2>"), and the program exits with a non-zero exitcode. - More detailed control over the output formatting will be possible in a later version with a "dumpstyle" option.
• --help, -h: print a help text and quit
• --resume-session: resume a session from the default session file (usually something like "/home/your_home/.retawq/session") in curses-like runmode
• --resume-session=filename: resume a session from the given file in curses-like runmode
• --rtcfg=letters: which run-time configuration shall actually be used; the letter "b" stands for "built-in" (cf. the compile-time configuration option OPTION_BIRTCFG), the letter "e" for "external file"; you can also combine both letters or leave them out completely; by default, all "existing" run-time configurations are used.
• --userdir=path: the path to a retawq user directory which usually contains at least a run-time configuration file; cf. the section "User Directory" in the user guide. By default, the user directory is something like "/home/your_home/.retawq/", depending on the environment variable "HOME"; this option allows you to use several profiles easily.
• --version, -v: print a short version information and quit

You can also specify the URLs of one or two documents which are then shown (in curses-like runmode).
