+"name \"jffs2_volume\", \"autoresize\" volume flag, and alignment 1. The\n"

+"volume from the \"../jffs2.img\" file. The size of the image file has to be\n"
+"less or equivalent to the volume size (30MiB). The \"mode=ubi\" line is\n"
+"mandatory and just tells that the section describes an UBI volume - other\n"
+"section modes may be added in the future.\n"
+"Notes:\n"
+" * size in vol_size might be specified kilobytes (KiB), megabytes (MiB),\n"
+" gigabytes (GiB) or bytes (no modifier);\n"
+" * if \"vol_size\" key is absent, the volume size is assumed to be\n"
+" equivalent to the size of the image file (defined by \"image\" key);\n"
+" * if the \"image\" is absent, the volume is assumed to be empty;\n"
+" * volume alignment must not be greater than the logical eraseblock size;\n"
+" * one ini file may contain arbitrary number of sections, the utility will\n"
+" put all the volumes which are described by these section to the output\n"
