// Unified method of accessing configuration values from environment variables,

// Given any config knob below that looks like this example:
//    RETAIL_CONFIG_DWORD_INFO(INTERNAL_LogEnable, W("LogEnable"), 0, "Turns on the traditional CLR log.")
//                                                                  ---------

// IMPORTANT: Before adding a new config value, please read up on naming conventions (see
// code:#NamingConventions)
//
// ==========
// CONTENTS
// ==========
// * How to define config values (see code:#Define)
// * How to access config values (see code:#Access)
// * Naming conventions (see code:#NamingConventions)
//
//
// =====================================
// #Define - Use one of the following macros to define config values. (See code:#DWORDs and code:#Strings)
// =====================================
//
// By default, all macros are DEBUG ONLY. Add the "RETAIL_" prefix to make the config value available in retail builds.
//
// #DWORDs:
// --------------------------------------------------------------------------
// CONFIG_DWORD_INFO(symbol, name, defaultValue, description)
// --------------------------------------------------------------------------
// Use this macro to define a basic DWORD value. CLRConfig will look in environment variables (adding
// COMPlus_ to the name) for this value. To customize
// where CLRConfig looks, use the extended version of the macro below. IMPORTANT: please follow the
// code:#NamingConventions for the symbol and the name!
//
// Example: CONFIG_DWORD_INFO(INTERNAL_AllowCrossModuleInlining, W("AllowCrossModuleInlining"), 0, "")
//
// --------------------------------------------------------------------------
// CONFIG_DWORD_INFO_EX(symbol, name, defaultValue, description, lookupOptions)
// --------------------------------------------------------------------------
// To customize where CLRConfig looks to get a DWORD, use the extended (_EX) version of the macro. For a list
// of options and their descriptions, see code:CLRConfig.LookupOptions
//
// Example: CONFIG_DWORD_INFO_EX(INTERNAL_EnableInternetHREFexes, W("EnableInternetHREFexes"), 0, "",
// (CLRConfig::LookupOptions) (CLRConfig::LookupOptions::DontPrependPrefix))
//
// #Strings:
// --------------------------------------------------------------------------
// CONFIG_STRING_INFO(symbol, name, description)
// --------------------------------------------------------------------------
// Defines a string value. Same rules apply as DWORDs.
//
// --------------------------------------------------------------------------
// CONFIG_STRING_INFO_EX(symbol, name, description, lookupOptions)
// --------------------------------------------------------------------------
// Extended version of the String macro. Again, similar to the DWORD extended macro.
//
//
// ===============================================================
// #Access - Use the following overloaded method to access config values.
// ===============================================================
// From anywhere, use CLRConfig::GetConfigValue(CLRConfig::<symbol>) to access any value defined in this
// file.
//
//
// ===============================================================
// #NamingConventions
// ===============================================================
// ----------------
// #Symbol - used to access values from the source. (using CLRConfig::<symbol>)
// ----------------
// The symbol for each config value is named as such:
// ### <Class>_<feature area>_<name> ###
//
// <Class> indicates which of the following buckets the value is in:
// * INTERNAL ? this value is for internal (CLR team) use only
// * UNSUPPORTED ? this value is available to partners/developers, but is not officially supported
// * EXTERNAL ? this value is available for anyone to use and is publicly documented
//
// Examples:
// * INTERNAL_Security_FullAccessChecks
// * UNSUPPORTED_Security_DisableTransparency
// * EXTERNAL_Security_LegacyHMACMode
//
// ----------------
// #Name - the name of the registry value or environment variable that CLRConfig looks up.
// ----------------
// The name of each value is the same as the symbol, with one exception. Names of external values do NOT
// contain the EXTERNAL prefix.
//
// For compatibility reasons, current names do not follow the convention.
//
// Examples:
// * W("INTERNAL_Security_FullAccessChecks")
// * W("UNSUPPORTED_Security_DisableTransparency")
// * W("Security_LegacyHMACMode") <---------------------- (No EXTERNAL prefix)
