Hi,
I am new latex but thank you for sharing. This is very useful for my thesis! Although it does compile but I do get errors with using this code. Apparently there is a missing number, treated as zero in line 29 and illegal unit of measure (pt inserted) in line 31 of abbreviations.tex. Also the '+' in line 17 of config.tex "\setlength{\labelwidth}{3cm}\setlength{\leftmargin}{\labelwidth+\labelsep}%" adds a plus to the list but removing the plus fixes the problem. Would you be able to have a look into this when you have time? Hopefully I will be able to help too but since I am new the errors are hard to understand. Thank you :)

Some issues (such as "@" ones) can come from inserting the code directly into the tex files. Converting abbreviations.tex into a .sty file (latex package) solves them.
