How to prevent my PSTricks codes from interfering the imported EPS files?

Question

My main input file not only contains PSTricks codes but also imports EPS images produced by epstool from standalone PSTricks input files compiled with dvips input.dvi -E -o output.eps.

I am worried whether the following warning that I got from epstool will endanger me.

The PostScript code must avoid using PostScript operators that would interfere with the embedding. These include operators with global effects such as changing the page size and changing the half tone screen.

How to make sure I am safe?

Answer 1

epstool --test-eps file.eps will attempt to test for some PostScript constructions that are forbidden or risky to use in EPS. I have never used this so I don't know how accurate it is.
