This family of functions is used internally to generate global option and environment variable names from the package name and internal option name.

envvar_name_generic(package, option) # "PACKAGE_OPTION"
A character value to use as the global option name or environment variable name
The package name and internal option name used for generating a global R option and environment variable name. As these functions are often provided as values, their arguments rarely need to be provided by package authors directly.
option_name_default(): A default naming convention, producing a global R option name from the
package name and internal option name (mypackage.myoption)
envvar_name_default(): A default naming convention, producing an environment variable name from the
package name and internal option name (R_MYPACKAGE_MYOPTION)
envvar_name_generic(): A generic naming convention, producing an environment variable name from the
package name and internal option name. Useful when a generic convention might
be used to share environment variables with other tools of the same name, or
when you're confident that your R package will not conflict with other tools.
