Cargo Features

gpl-session has no features set by default.

[dependencies]
gpl-session = { version = "2.0.0", features = ["no-entrypoint", "no-idl", "no-log-ix-name", "cpi"] }
no-entrypoint cpi? = gpl-session-macros
no-idl
no-log-ix-name
cpi = no-entrypoint

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
