The DOCUMENT directory contains documentation that is considered to be
either necessary or useful for users to understand the archive data sets.
Documents may be included in multiple forms (ASCII, PDF, MS Word, HTML
with image file pointers, etc.). Documents in different formats are
included in subdirectories that collect together those with the same
content. Included are the following documents.

<DOCUMENT> DOCINFO.TXT: Identifies and describes the function of each
file in the DOCUMENT directory. (This File)

<DOCUMENT\CDR_SIS> EPPS_CDR_SIS.TXT:  The EPPS CDR SIS: "MESSENGER
Software Interface Specification for the Calibrated Data Records of the
Energetic Particle and Plasma Spectrometer" in ASCII text format. Only
the text is provided; for illustrations, tables, etc. one of the other
formats should be consulted.

<DOCUMENT\CDR_SIS> EPPS_CDR_SIS.PDF:  The EPPS CDR SIS: "MESSENGER
Software Interface Specification for the Calibrated Data Records of the
Energetic Particle and Plasma Spectrometer" in Adobe Acrobat format.
Note that, in contrast to the .TXT version, the illustrations, tables,
etc. will display appropriately.

<DOCUMENT\CDR_SIS> EPPS_CDR_SIS.LBL: The detached label for the various
EPPS CDR SIS files.
