; ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
;
; Desc.: This is a translator script for german and english which works
;	 bidirectional, e.g. you can do !leo <english word> to get the
; 	 german translation and vice versa. I'ts based on the well-known
; 	 website 'http://dict.leo.org'.
;
; ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
;
; Syntax with default settings:
;
;	 !leo <word>
;
; Examples:
;
;	 !leo to sneeze
;	 !leo Kuh
;
; ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
;
; Settings:
;
;   - public trigger (default: !leo)
;
alias -l leo.trigger { return !leo }
;
;
;   - target (put either notice, channel or query there)
;
alias -l leo.target { return notice }
;
;
;   - number of max. results in output (default: 7)
;
alias -l leo.results { return 7 }
;
;
;   - linking (put on or off) adds the URL to the results
;     page to the output
;
alias -l leo.linking { return on }
;
;
;   - Channels to exclude (separate by comma)
;
alias -l leo.exclude { return #help,#help.script,#scripting }
;

; Don't edit anything below here unless you know what you're
