+;;; HELP TEXTS
+(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
