It's necessary sometimes, if you're building an operating system for example, to insert special instructions here and there without the compiler's interference. That's the kind of thing asm() is for. gcc will insert raw assembly if you ask, but you really have to know what you're doing since it can't protect you( though some more advanced syntax lets you warn gcc about side-effects instead). Plain, non-ASM goto (yes, it exists, very rarely used) wouldn't let you jump out of bounds.

djvu2hocr

DJVU2HOCR(1)							 djvu2hocr manual						      DJVU2HOCR(1)

NAME

       djvu2hocr - DjVu to hOCR converter

SYNOPSIS

       djvu2hocr [option...] djvu-file

       djvu2hocr {--version | --help | -h}

DESCRIPTION

       djvu2hocr converts hidden text from a DjVu file to the hOCR[1] format.

OPTIONS

   Text segmentation options
       --word-segmentation=simple
	   Use the same word segmentation as found in the DjVu file.

	   This is the default.

       --word-segmentation=uax29
	   Use the Unicode Text Segmentation[2] algorithm to break lines into words, possibly fixing word segmentation found in the DjVu file.

   Other options
       --version
	   Output version information and exit.

       -h, --help
	   Display help and exit.

PORTABILITY

       djvu2hocr uses a custom extension to hOCR to retain characters which cannot be directly represented in an HTML/XML document. For example,
       control character BEL (^G, U+0007), is converted into the following HTML chunk: <span class="djvu_char" title="#x07"> </span>
