    NAME
           xml2pib - Qualcomm Atheros XML driven PIB editor

    SYNOPSIS
           xml2pib [options] pib-file [pib-file] [...]

    DESCRIPTION
           The  Atheros  PIB  XML  Editor  modifies an Atheros PIB file based on XML instructions defined in one or more instruction
           files.  Instruction files must be valid XML and conform to schema file piboffset.xsd or errors will occur.  Always  vali‐
           date  XML files against this schema with a validating parser before submitting them to this program.  Firefox or Internet
           Explorer are suitable for validation purposes purpose.

           This program is part of the Qualcomm Atheros Powerline Toolkit.  See the AMP man page for an  overview  and  installation
           instructions.

    OPTIONS
           -f filename
                  The  XML  instruction  file.   XML instruction files must conform to the Qualcomm Atheros scheme designed for this
                  purpose.  If more that one .xml file is specified then edits are applied in order of filename such that later edit
                  instructions  can  over-write eariler instructions.  Instruction files usually have a .xml extension but this pro‐
                  gram makes no assumption based on filename and does not enforce any filename conventions.

           -o     Print the appropriate XML schema on stdout.  This schema should be used to validate XML instructions using a vali‐
                  dating parser such as Firefox or Microsoft Internet Explorer.

           -q     Suppresses printing of progress messages.  This option has no effect at this time.

           -v     Print additional information.  This option has no effect at this time.

           -?,--help
                  Print program help summary on stdout.  This option takes precedence over other options on the command line.

           -!,--version
                  Print program version information on stdout.  This option takes precedence over other options on the command line.
                  Use this option when sending screen dumps to Atheros Technical Support so that they know exactly which version  of
                  the Linux Toolkit you are using.

    ARGUMENTS
           pib-file
                  An Atheros parameter filename.  Only one parameter file can be edited at a time and so care must be taken to avoid
                  the use of wildcard filenames.  Parameter files usually have a .pib extension but this program makes no assumption
                  based on filename and does not enforce any filename conventions.

    SCHEMA
           The official Atheros XML PIB Edit schema follows.  It defines general instruction file structure and the elements used to
           edit PIB files.  This file should be a controlled document and instruction files should always be  validated  against  it
           before using them to edit a PIB file.  An explanation of this file appears below.

    ELEMENTS
           <pib>  The Parameter Information Block subject to edit.  There is exactly one pib defined in an instruction file.

           <object>
                  A  data region withn a pib.  There must be at least one object defined inside a pib.  Each object has an offset, a
                  length and data where data is expressed as one dataString, a dataByte, a dataHex or an array as  described  below.
                  The name attribute optional but may be used for clarity or for reporting purposes.

           <offset>
                  The  relative  position  of the object in bytes expressed in hexadecimal.  The offset plus the length of an object
                  cannot exceed PIB length or an error will occur.  The offset and length element can appear  in  either  order  but
                  both must appear before the data element.  The offset element is required.

           <length>
                  The  extent  of  the  object  expressed  in  decimal bytes.  The offset plus length of an object cannot exceed PIB
                  length.  The the offset and length elements can occur in either order but both must precede the data element.  The
                  length  element  is required for elements array and dataString but may be omitted for elements dataHuge, dataLong,
                  dataWord and dataByte.

           <array>
                  A sequence of dataByte and/or dataHex elements.  The implied length is determined by array members but must  equal
                  the object length attribute or an error will occur.  A dataString is illegal inside an array.

           <dataString>
                  Any  sequence  of  printable  characters.  The implied length is 1 byte longer than the number of characters.  The
                  string will be truncated or padded with NUL bytes  to  match  the  object  length  attribute.   An  object  length
                  attribute of 0 stores one NUL byte.  A dataString element is illegal within an array block.

           <dataHuge>
                  A  unsigned  decimal  integer string that represents any 64 bit binary value.  The implied length is 8 bytes.  The
                  object length attribute is ignored and may be omitted.

           <dataLong>
                  A unsigned decimal integer string that represents any 32 bit binary value.  The implied length is  4  bytes.   The
                  object length attribute is ignored and may be omitted.

           <dataWord>
                  A  unsigned  decimal  integer string that represents any 16 bit binary value.  The implied length is 2 bytes.  The
                  object length attribute is ignored and may be omitted.

           <dataByte>
                  An unsigned  decimal digit string that represents any 8 bit binary value.  The implied  length  is  1  byte.   The
                  object length attribute is ignored and may be omitted.

           <dataHex>
                  A  hexadecimal  digit  string that represents one byte for each digit pair (octet) present.  There must be an even
                  number of digits or an error will occur.  The resulting length must equal  the  object  length  unless  the  value
                  appears inside an array.  Inside an array, the resulting length must not exceed the remaining array length.

    PROCESS
           The  program  reads  one PIB file and replaces selected values with new ones, computes the new checksum and re-writes the
           file.  New values are defined by offset, length, format and value.  The object name  is  actually  irrelevant.   Critical
           values  are the offset, length and data type/value.  Obviously, care must be taken when specifying offsets and lengths to
           avoid editing objects incorrectly.

    INSTRUCTIONS
           An example instruction file follows.  It references the Qualcomm Atheros XML PIB Edit schema file, piboffset.xsd, that is
           shown  above  so  that  a  validating  parser can find the schema and perform document checks.  The remainder of the file
           describes a series of object names, offsets, lengths and values that describe the edits to be performed.

    EXAMPLES
           The following example reads PIB file abc.pib and edits it according to instructions found in XML file local.xml.  The PIB
           file is always specified first, followed by one or more XML instruction files.

                   # xml2pib abc.pib local.xml

           The  following  example reads PIB file abc.pib and edits it according to three XML instruction files, in the order speci‐
           fied.  Order can be critical since later edits could over-write earlier edits.

                   # xml2pib abc.pib standard.xml custom.xml errata.xml

           The following example does nothing because no instruction files are specified.

                   # xml2pib abc.pib
