What is the easiest way to switch from a document with color graphics to one with grayscale graphics?
I have various
fig/ directories that contain my color graphics, and I already have corresponding
fig-gray/ directories that contain the same graphics in grayscale.
path1/fig/foo.pdf path2/fig/bar.pdf path1/fig-gray/foo.pdf path2/fig-gray/bar.pdf
includegraphics commands in various included .tex files, e.g.
Now what is the easiest way to tell LaTeX to switch to using the
fig-gray/ directories instead? (I'd like to avoid having to preprocess my .tex files with search and replace.)
