CLIT(1) General Commands Manual CLIT(1)
NAME
clit - program to manipulate Microsoft Reader .LIT files
SYNOPSIS
1. clit [options] litfile.lit subdir/
2. clit [options] oldfile.lit newfile.lit
3. clit [options] oldfile.lit newfile.lit inscription
DESCRIPTION
This manual page documents briefly the clit command.
ConvLIT is a program to convert Microsoft Reader format eBooks [LIT] into an open format. clit supports three modes of operation:
1. Explosion: expanding a LIT file into an OEBPS compliant package, that is the original XML / HTML source.
2. Downconverting: converts to DRM1 format, also known as sealing the LIT file.
3. Inscribing: similar to #2, this adds a label, or inscription, to the ebook to mark that it belongs to you.
OPTIONS
A summary of options is included below. For a complete description, run the program without any arguments.
-d Disable creating multiple subdirectories.
-h Show summary of options.
-k /path/to/keys.txt
The DRM5 key file is assumed to be called keys.txt and located in the current directory. If not, use this option to instruct Con-
vLIT where to find the key file.
