[fpc-pascal] helpsystem, some numbers

[Marco van de Voort]

This morning I did a bit research after the help files, I hope it sheds some
light on the WHY for the recent CHM efforts:

                     html           html
help package    size on disk(k)  real size(k) chm(k)
rtl                38816          22096       1865   
lcl		   107404         72499       5227
fcl                8548            5148        445
-------------------------------------------------------
All                154768         99743       7537           

The disk is NTFS, so probably 4kb clustersize.

Total html bzip2'ed :  2.9MB or so 
Total html zipped   :  25MB       
total chm  bzip2'ed :  6,7MB      

Extraction time html: 1 minute+ (Core 2 6600 (2.4GHz), winXP's unzip)
Extraction time chm : not measurable.

Note that while the bzip2 archive is very small, it must be unpacked
entirely before use, contrary to either zip (in theory you could open the
zip and extract only the one file) and chm (which has several indexes
internally too, the unpacked chm is possibly larger than the html due to
this)
