+
+You can enable OCR support for pdf,xps,cbz,fb2,epub file types with the
+`--ocr <lang>` option. Download the language data files with your
+package manager (`apt install tesseract-ocr-eng`) or directly [from Github](https://github.com/tesseract-ocr/tesseract/wiki/Data-Files).
+
+The `simon987/sist2` github image comes with common languages 
+(hin, jpn, eng, fra, rus, spa) pre-installed.
+
+Examples
+```bash
+sist2 scan --ocr jpn ~/Books/Manga/

+/** @file opc/container.h
+
+ The container.h module has the fundamental methods for dealing with ZIP-based OPC container. 
+ 
+ OPC container can be opened in READ-ONLY mode, WRITE-ONLY mode, READ/WRITE mode, TEMPLATE mode and TRANSITION mode. 
+ The most notable mode is the READ/WRITE mode, which gives you concurrent stream-based READ and WRITE access to a 
+ single ZIP-based OPC container. This is achieved without the use of temporary files by taking advantage of the 
+ OPC specific “interleave” mode. \see http://standards.iso.org/ittf/PubliclyAvailableStandards/c051459_ISOIEC_29500-2_2008(E).zip
+ 
+ The TEMPLATE mode allows very fast customized "cloning" of ZIP-based OPC container by using "RAW access" to the ZIP streams. 
+ The TRANSITION mode is a special version of the TEMPLATE mode, which allows transition-based READ/WRITE access to the 
+ ZIP-based OPC container using a temporary file.
