+pdflatexpicscale will downscale large raster images for your TeX project
+to reasonable size.
+Basic usage:
+ pdflatexpicscale myarticle
+where your main LaTeX file is called 'myarticle.tex' and a log file exists.
+Fine tuning:
+--destdir=folder (relative path, must exist,
+ defaults to 'printimg' subfolder of current folder)
+--srcdir=folder (folder to find original images, if this software
+ can't figure it out on it's own, because you already
+ used the target directory.)
+--printdpi=XXX (default 300)
+--tolerance=XX (default 20 Percents over printdpi to ignore scaling)
+--verbose (if you want to know what the script attempts to do)
+--version (show software version)
+_endusage
