Usage

This program can be used to work with FAT12 floppy images.

Usage: fat_imgen -c [-F] -f IMG-FILE [-i FILE [-n FILENAME]] [-s FILE]
  or:  fat_imgen -m -f IMG-FILE -s FILE
  or:  fat_imgen -m -f IMG-FILE -i FILE [-n FILENAME]
  or:  fat_imgen -m -f IMG-FILE -i FILE [-n FILENAME] -s FILE
  or:  fat_imgen -e [-F] -f IMG-FILE
  or:  fat_imgen -e [-F] -f IMG-FILE [-o FILE] -x FILE
  or:  fat_imgen -b [-F] [-o FILE]

Main operation mode:
  -c                      Create an image.
  -m                      Modify an image.
  -e                      Extract files from an image.
  -b                      Create a standard FAT12 boot sector.
                          (Without -o, defaults to `bootsect.bin'.)

File selection:
  -f IMG-FILE             Use IMG-FILE as the image file.
  -s FILE                 Use FILE as boot sector in the image.
  -i FILE                 Insert FILE into the image.
  -n FILENAME             Use FILENAME as the filename of the inserted file.
  -x FILE                 Extract FILE from the image.
  -o FILE                 Write output to FILE.

Generic modifiers:
  -F                      Overwrite the output file (e.g. image, boot sector).

Informative output:
  --help                  Display this information.
  --version               Display version information.
