Lots of temporary files when generating png files

[Anthony Rushforth]

Hello,

I use this command line to generate png files :
lilypond  -dbackend=eps -dno-gs-load-fonts -dinclude-eps-fonts
-dpixmap-format=pngalpha -dresolution=100 --png c1c1e1g1.ly

I took the command line from
http://lilypond.org/doc/v2.19/Documentation/usage-big-page#lilypond-output-in-other-programs

It generates these files :
c1c1e1g1-1.eps
c1c1e1g1-systems.count
c1c1e1g1-systems.tex
c1c1e1g1-systems.texi
c1c1e1g1.eps


Is it possible to avoid these files or put them in another location ?
