Before this patch `-nghttp3`/`-ngtcp2` had an effect only when `-ssl`
was also enabled. `-ssl` meaning OpenSSL (and its forks). After
8a13be227e nghttp3/ngtcp2 can also be
used together with wolfSSL. This patch adds the ability to enable
`-nghttp3`/`-ngtcp2` independently from `-ssl` (OpenSSL), allowing to
use it with wolfSSL or other, future TLS backends.
Before this patch, it was fine to enable `-nghttp3`/`-ngtcp2`
unconditionally. After this patch, this is no longer the case, and now
it's the user's responsibility to enable `-nghttp3`/`-ngtcp2` only
together with a compatible TLS backend.
When using a TLS backend other than OpenSSL, the TLS-specific ngtcp2
library must be configured manually, e.g.:
`export CURL_LDFLAG_EXTRAS=-lngtcp2_crypto_wolfssl`
(or via `NGTCP2_LIBS`)

you will find a mix of various documentation in this directory and
subdirectories, using several different formats. Some of them are not ideal
for reading directly in your browser.
If you would rather see the rendered version of the documentation, check out the
curl website's documentation section for
general curl stuff or the libcurl section for
libcurl related documentation.
