Maybe there should be an "auto" folder at every .tex file location instead

of only in the master location, I imagine this could solve a few of the

issues. The path to the .el file would have to be constructed using

"../", then the path to the included file, then "auto/" and finally the

filename. In my example, the paths to the .el files in the master's .el

file would end up as follows:

"../auto/preamble0",

"../auto/prea mble1"

"../../../auto/preamble2"

"../auto/preamble3"

"../folder/auto/preamble4"

"../../auto/preamble5"
