By using one fixed configuration file, this program is very well suited for being used in batch processing. Once the mapping of which Frame-paragraph-tag is becoming which HTML-tag is done in that config file, the number of files to convert doesn't matter. And if there isn't a precise HTML-tag that corresponds to one of the Frame-paragraph-tags, arbitrary HTML-code can be put into that place. If whole books (consisting of several Frame input files) are converted, links between these files are maintained properly. Graphics are automatically converted to GIF (with links to PostScript files for higher-resolution output), tables are converted into preformatted ASCII-tables with a link to a PostScript file displaying the table in higher quality.
One of the drawbacks is that document seperation has to be done manually, the converter generates one HTML file from each Frame-input-file. Generation of automatic indices is not supported, the converter just warns about unused index points (see below for a patch). Sub- and superscript are not supported.
About the biggest drawback of frame2html however is that it is no longer supported by the author.
