+Error Code Lookup for gPXE
2
+==========================
3
+This program looks up gPXE error codes so you can locate the line of source
4
+code which produced the error.
5
+
6
+Setup
7
+-----
8
+You must run:
9
+./build_errcodedb.py >errcodedb.py
10
+
11
+This extracts error code definitions from the gPXE source code and produces a
12
+"database" which is used by the main program.
13
+
14
+Once you have done this errcode.py and errcodedb.py are the only files you
15
+need.  They are now independent of the gPXE source code and can be moved
16
+anywhere.
17
+
18
+[OPTIONAL]
19
+A PHP script is provided as a web interface.  First edit errcode.php to point
20
+$ERRCODE_PATH to the errcode.py script.  Then move errcode.php to a location
21
+visible from your web server.
22
+
23
+Usage
24
+-----
25
+Looking up error codes on the command-line:
26
+./errcode.py 0x12345678
27
+
28
+Further information
29
+-------------------
30
+See http://etherboot.org/.
