+Here's the webserver API, so you can work on the webserver.
+
+My personal goal is to make this interface simple, so that coding it
+will be like coding in some scripting language...
+
+
+
+char *get_param(char in_string[500], char swhat[500]);
+
+This function simply returns various data from the query string.
+ *Pass get_param NOTHING longer than 500 in length!
+
+ What do I pass where in_string is?
+ The query string.
+
+ What do I pass where swhat is?
+ One of two things...
+ Either 0 for the path of the 'page'
+ or you can pass it the param you wish to lookup.
+
+
+
+
+
+
+char *get_query(char *inquery);
+
+This function simply returns a query string from the raw server request.
+This is used once in main, I doubt you'll need it.
+
+
+
+
+
+void web_send(int sockin, char *in_data);
+
+Super easy way of sending data to a webpage!
+Simply put in the socket name and then the data.
+
+ Ex:
+ web_send(socket, "I like cheese!\n");
+
+
+
+
+char *html_header(char* title);
+Easy way to print the eAthena header for the server.
+
+ Ex:
+ web_send(sockethere, html_header("About"));

+This readme is intended for the programmers of eAthena.
+
+This webserver's apis are in API.txt.
+
+To make this simple, generate.c should handle most of the work this sever does
+in terms of what people see.
+
+When a request is made the server shoots it off to generate.c.
+
+You are welcome to create more functions used by generate.c to generate pages
+though, so don't feel limited by that one file.
