360# 1. Add a backslash before any :, = or ! that do not have a backslash already.
361# 2. Apply the file unicode2x.sed which does a whole bunch of \u00XX to \xXX
362#    conversions.
363# 3. Delete all lines starting with #.
364# 4. Delete empty lines.
365# 5. Append lines ending with \ with the next line.
366# 6. Remove leading and trailing white space. Note that tabs must be explicit
367#    as sed on macosx does not understand '\t'.
368# 7. Replace the first \= with just =.
369# 8. Finally it's all sorted to create a stable output.

371# It is assumed that = is the character used for separating names and values.
