Log content is appended to the end of the log file, preserving existing contents.
There are two options which turn off parts of the squeezer. They are \texttt{-squeeze-no-recompress} for avoiding the reprocessing of compressed sections (especially useful if they are malformed), and \texttt{-squeeze-no-pagedata} for avoiding the reprocessing of page data (ditto). These two options also make the process much faster at the cost of a little less compression. Experiment. The option \texttt{-squeeze-no-pagedata} avoids the reprocessing of page data, which avoids problems in case of malformed files, and makes the process much faster at the cost of a little less compression. The option \texttt{-squeeze-no-recompress} is deprecated as of version 2.6 and has no effect.
