            "content": "Reads a Lisp Machine bitmap as input.  Produces a portable graymap as output.\n\nThis  is  the  file format written by the tv:write-bit-array-file function on TI Explorer and\nSymbolics lisp machines.\n\nMulti-plane bitmaps on lisp machines are color; but the lispm image file format does not  in‐\nclude a color map, so we must treat it as a graymap instead.  This is unfortunate.\n",

        "BUGS": {
            "content": "The  Lispm  bitmap  file format is a bit quirky;  Usually the image in the file has its width\nrounded up to the next higher multiple of 32, but not always.  If the width is not a multiple\nof  32,  we  don't deal with it properly, but because of the Lispm microcode, such arrays are\nprobably not image data anyway.\n\nAlso, the lispm code for saving bitmaps has a bug, in that if you are writing a bitmap  which\nis  not mod32 across, the file may be up to 7 bits too short!  They round down instead of up,\nand we don't handle this bug gracefully.\n\nNo color.\n",
