+== NAME ==
+pxechn.c32 - Chainboot to new Network Boot Program (NBP)
+
+
+== SYNOPSIS ==
+[verse]
+*pxechn.c32* [-h | --help | -?]
+*pxechn.c32* -r 'FILE'
+*pxechn.c32* 'FILE' ['OPTIONS']
+
+
+== DESCRIPTION ==
+Chainboot to a new Network Boot Program (NBP) 'FILE' with options to
+adjust PXE packet #3 (PXENV_PACKET_TYPE_CACHED_REPLY) to alter end
+behavior.  'FILE' may be a filename, an IP::FN (
+192.168.1.1::path/to/file.0 ), or URL.  'FILE' is parsed to adjust the
+DHCP 'sname' field/option 66 and 'file' field/option 67.
+// but these may be override-able in the future.
+
+
+== OPTIONS ==
+*-c* 'CONFIG'::
+    'config' file for PXELINUX (DHCP Option 209).
+
+// *-f* 'MOD'::
+//     'Force' behavior specified by modifier 'MOD'
+//
+// *-g* 'HOST'::
+//     Set 'gateway'/relay DHCP field to 'HOST'.  Parsed by pxe_dns().
+//
+*-h*, *--help*, *-?*::
+    Print 'help'/usage information; invalid options will also cause
+    this.
+
+// *-n*::
+//     Use 'native' methods, ignoring underlying gPXE/iPXE.
+// 
+// *-N*::
+//     Use 'non-native' methods to utilize gPXE/iPXE (if available).
+//
+*-o* 'OPT.TYPE=VALUE'::
+    Set 'option'.  'OPT' is in 'DECIMAL INPUT' format (below).  'TYPE'
+    specifies the output type and input syntax (listed here in quotes
+    and at present, 1 character).  ''b'yte', ''w'ord'(2B), ''l'ong'(4B),
+    ''q'uad'(8B), character ''s'tring' and colon-separated 'he'x''
+    string (case insensitive; bytes must have 2 digits and each byte
+    must be separated).  byte, word, long and quad input values must
+    meet criteria for 'DECIMAL INPUT'
+
+*-p* 'PATH'::
+    'path' option for PXELINUX (DHCP Option 210).
+
+*-r*::
+    'restart'.  Call the PXE stack with PXENV_RESTART_TFTP.  _Must_ be
+    the only option and before 'FILE'.
+
+*-S*::
+    Set 'sip' based on sname field/option 66 (by direct IP if a
+    period-delimited address or otherwise DNS).
+
+*-t* 'SECONDS'::
+    'timeout' option for PXELINUX (DHCP Option 211).
+
+// *-u*::
+//     Copy 'UUID' (Option 97) if found in packet #1
+
+*-w*::
+    'wait'.  After loading, wait for user input before booting.
+
+*-W*::
+    Enable 'WDS' (Windows Deployment Services) - specific options. 
+    'FILE' (or its overrides for DHCP fields siaddr and file) must point
+    at the WDS server.
+    *NOTE:* As of 2012-05-31, there is a known issue with gPXE/iPXE, at
+    least with undionly.kkpxe.
+// PXELINUX asks gPXE/iPXE to unload, reverting to an underlying stack
+
+
+== DECIMAL INPUT ==
+All parameters that are defaulted to decimal format are processed by
+*strtoul*(3) with a base of 0 which allows alternate formats and finds a
+suitable non-space separating character.
+
+
+== EXAMPLES ==
+`pxechn.c32 http://myhost.dom.loc/path/nbp.0 -c myconfig`::
+    Load nbp.0 and set PXELINUX config (option 209).
+
+`pxechn.c32 gpxelinux.0 -p http://10.1.1.4/tftp/ -w -c myconfig -o 15.s=domain.loc -o 6.x=0A:01:01:02:ac:17:4D:Ec -`::
+    Load gpxelinux.0 from the current directory, set prefix, wait to
+    execute, set first config, set the domain name and 2 domain name
+    servers (case mixed to show insensitivity; 10.1.1.2 and
+    172.23.77.236).
+
+`pxechn.c32 gpxelinux.0 -p http://10.1.1.4/tftp/ -w -o 0xA0.x=12:34:56:78 -x 197.x=00:d0:de:00`::
+    Load gpxelinux.0 (relative to the current directory and not
+    altering sname/option 66), set the PXELINUX path prefix, wait after
+    loading, set option 160 to 0x12 0x34 0x56 0x78, and option 197 to
+    0x00 0xD0 0xDE 0x00.
+
+`pxechn.c32 10.1.1.8:boot\x86\wdsnbp.com -W`::
+    Load wdsnbp.com from 10.1.1.8 and copy DHCP Option 66 to DHCP
+    field sname if there's room.
+ 
+`pxechn.c32 10.1.1.4:boot\x86\wdsnbp.com -W -o 66.x=0a:01:01:08 -S`::
+    Load wdsnbp.com from 10.1.1.4, point packets to 10.1.1.8 for use
+    with WDS, copy DHCP Option 66 to DHCP field sname if there's room
+    and decode this to an IPv4 address.
+
+
+== NOTES ==
+Please note that some NBPs may ignore packet #3 by either not examining
+it at all or by issuing its own DHCP DISCOVER/REQUEST, negating all DHCP
+field/option modifications by pxechn.c32, including Microsoft Windows
+Server 2008R2 WDS's wdsnbp.com.  See also option '-W'.
+
+URL specifications in 'FILE' that include user/password before the host
+will currently cause the siaddr field to not be set properly.
+
+The non-space constraint is due to how Syslinux variants parse the
+command line as of 2012-09-16.
