This is simple yet complete WebServer library for AVR, Portenta_H7, Teensy, SAM DUE, SAMD21/SAMD51, nRF52, STM32, RP2040-based, etc. boards running Ethernet shields. The functions are similar and compatible to ESP8266/ESP32 WebServer libraries to make life much easier to port sketches from ESP8266/ESP32. Coexisting now with `ESP32 WebServer` and `ESP8266 ESP8266WebServer` libraries. Ethernet_Generic library is used as default for W5x00 with custom SPI

Portable C libraries which provide APIs to build applications with u-blox products and services. Delivered as add-on to existing microcontroller and RTOS SDKs.
