[csw-maintainers] TeXLive packaging take almost 3 days

[pfelecan at opencsw.org]

I'm struggling to replace teTeX with TeXLive since July... Quite a big
endeavor. Here are some statistics:

 112180 files in the installation directory

 87 packages

I'm using the split as defined by Debian with some adaptations.

The time taken for each package is summarized in the following table:

Most of the time is spent in cswproto and patfilter utilities.

For example: for libkpathsea6 the usage is the following:

  cswproto:

	 real 1223.12
	 user 1092.55
	 sys 139.96

         of which 1077 by repeated calls to pkgproto

 pathfilter:

	 real 2183.69
	 user 2182.79
	 sys 0.72

IMHO, there is place for some optimization.

If there is a kind soul to help on this he'll have my gratitude.
