mylatexformat – Build a format based on the preamble of a LaTeX file

The use of for­mats helps to speed up com­pi­la­tions: pack­ages which have been dumped in the for­mat are loaded at very high speed. This is use­ful when a doc­u­ment loads many pack­ages (in­clud­ing large pack­ages such as pgf-TikZ).
The pack­age was de­vel­oped from the work in my­la­tex, and elim­i­nates many of the lim­i­ta­tions and prob­lems of that pack­age.
