31 Extract a date range from a squid log file and write it into a separate file.
33 It can optionally convert the date in human readable format.
35 The output can be split by day into separate files.
37 \param arq The squid log file to split.
38 \param df The date format if the date is to be converted in human readable form. Only the first
39 character is taken into account. It can be 'e' for European date format or anything else for
41 \param dfrom The first date to output in the form (Year*10000+Month*100+Day).
42 \param duntil The last date to output in the form (Year*10000+Month*100+Day).
43 \param convert \c True if the date must be converted into human readable form.
44 \param splitprefix If not empty, the output file is written in separate files (one for each day) and
45 the files are named after the day they contain prefixed with the string contained in this variable.
