$NAME - convert a DRM1 .lit file to .epub
|
|
|
|
Usage: $NAME input.lit [ output.epub ]
|
|
|
|
Default output file is written to the current directory, named after the
|
|
input filename with the .lit or .LIT extension changed to .epub, or the
|
|
input filename with .epub appended, if there is no .lit extension.
|
|
|
|
Use - for the output file, to output to stdout.
|
|
|
|
Exit status is 0 on success, non-zero on failure.
|
|
|
|
If you need to convert a non-DRM1 .lit file, use convertlit to downconvert
|
|
to DRM1 first.
