My first "usable" software - tiff2djvu
Last day I created an app called tiff2djvu, mainly intended for wikisource users. It is for Ubuntu OS (I haven't tested on others) and is written using Python. While using Scan Tailor to correct scanned images, the outputs are TIFF images. Inorder to upload them to wikisource, we need to convert them to a single DJVU file. This software does this purpose. Thanks for Manojettan for the idea and Hrishi for technical support.
The software can be found here.
Please read the README file to get information about prerequisites.
