-(defparameter +invite-help-text+
-  " 
-New contributor accounts are added to the your oneliners server by
-redeeming invite tokens.
-
-When the --redeem option is passed, the ARGS section is expected to be
-three items long, and is interpreted as TOKEN USERNAME PASSWORD. E.g.:
-
-    ol --redeem PHONEYTOKEN c00lhacker my1337pw 
-
-Would attempt to make a new user named c00lhacker with password
-my1337pw.")
-
-(defparameter +oneliners-variables-help-text+
-"
-Oneliners may contain variables.  There are positional variables and
-named variables.
-
-POSITIONAL VARIABLES appear in the oneliner as a # followed by a
-number, which must 1 or greater.  For example:
-
-    echo Hello #1, Happy #2
-
-The #1 and #2 are a positional variables. You might call the above
-like
-
-   ol --run 8 Doofus Tuesday
-
-Assuming that the above oneliner has ID 8, then \"Hello Doofus,
- Happy Tuesday\" would print to the console.
-
-NAMED VARIABLES are similar. They appear in the oneliner as # followed
-by a letter in the Roman alphabet, followed by any sequence of Roman
-letters, numbers, or the symbol _.  For example:
-
-   echo Hello #name you get a #thing
-
-The #name and #thing are named variables. You might call the above like so:
-
-  ol --run 3 name=Goober thing='sock in the nose'
-
-Which should print \"Hello Goober you get a sock in the nose\".
-
-Finally, you can MIX POSITIONAL AND NAMED VARIABLES so long as, when
-you run the oneliner, all positional variables appear first.
-")
-
-(defparameter +configure-your-edtior+
-  "Adding explainations for oneliners, either with --add or --edit,
-will use a default system editor. If you do not like the default
-editor you may configure it by the exporting the EDITOR environment
-variable to whatever you prefer.
-
-E.g. in your .bashrc you might put 
-
-export EDITOR=/usr/bin/zile
