My understanding is that we use "number" for discrete variables and
"amount" for continuous variables.
So you can say "The amount of flour required depends on..." or, "Last
night I consumed a large amount of beer!".
And, "That tank contains a large number of fish" or, "Over the week I
consumed a number of cases of beer."
I think that features are discrete, so the man page would read "...the
number of features will make your head spin!".
curl offers a busload of useful tricks like proxy support, user
authentication, ftp upload, HTTP post, SSL connections, cookies, file transfer
-resume and more. As you will see below, the amount of features will make your
+resume and more. As you will see below, the number of features will make your
head spin!
curl is powered by libcurl for all transfer-related features. See
