"
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 8 Doofus Tuesday
Assuming that the above is the 8th search result, then \"Hello Doofus,
Happy Tuesday\" would print to the console.
NAMED VARIABLES are similar. They appear in the oneliner as # followed
by an 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 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.
