I've just published draft #6 of SRFI 170.  It was
submitted by John Cowan, author of the SRFI, with
much assistance from Harold (HGA).

    procedures

    standards to Rationale

  - XSI extensions added to file-info (stat)

  - Excise /var/tmp as the default or example tmp
    dir location

    project

  - Minor language, typo, indentation fixes,
    regularize "file name(s)"

  - Add . and .. exceptions to read-directory, add
    paragraph break

  - Remove unreliable sync-file and
    sync-file-system proceedures

  - Based on file-info-*? description, perms/mode

    timespec argument diff

    obsolete with /tmp default
