Global variables
================

   Global flags may be set to 1 or to 0.

   The following global flags are recognized:

`MTOOLS_SKIP_CHECK'
     If this is set to 1, mtools skips most of its sanity checks. This
     is needed to read some Atari disks which have been made with the
     earlier ROMs, and which would not be recognized otherwise.

`MTOOLS_FAT_COMPATIBILITY'
     If this is set to 1, mtools skips the fat size checks. Some disks
     have a bigger FAT than they really need to. These are rejected if
     this option is not set.

`MTOOLS_LOWER_CASE'
     If this is set to 1, mtools displays all-upper-case short
     filenames as lowercase. This has been done to allow a behavior
     which is consistent with older versions of mtools which didn't
     know about the case bits.

`MTOOLS_NO_VFAT'
     If this is set to 1, mtools won't generate VFAT entries for
     filenames which are mixed-case, but otherwise legal dos filenames.
     This is useful when working with DOS versions which can't grok
     VFAT longnames, such as FreeDos.

`MTOOLS_DOTTED_DIR'
     In a wide directory, prints the short name with a dot instead of
     spaces separating the basename and the extension.

`MTOOLS_NAME_NUMERIC_TAIL'
     If this is set to one (default), generate numeric tails for all
     long names (~1).  If set to zero, only generate numeric tails if
     otherwise a clash would have happened.

`MTOOLS_TWENTY_FOUR_HOUR_CLOCK'
     If 1, uses the European notation for times (twenty four hour
     clock), else uses the UK/US notation (am/pm)

   Example: Inserting the following line into your configuration file
instructs mtools to skip the sanity checks:
       MTOOLS_SKIP_CHECK=1

   Global variables may also be set via the environment:
       export MTOOLS_SKIP_CHECK=1

   Global string variables may be set to any value:
`MTOOLS_DATE_STRING'
     The format used for printing dates of files.  By default, is
     dd-mm-yyyy.
