Reference

Look-up tables and pointers into the source for things that are easier to find than to remember.

Page	What it lists
Configuration	Build flags, runtime config files, environment variables
Dependencies	Third-party libraries curl can link against

The deeply-detailed surface (every option, every callback) is in docs/cmdline-opts/ and docs/libcurl/opts/. The rendered man pages are at https://curl.se/docs/manpage.html and https://curl.se/libcurl/c/.
