Revision 1.7, Fri Nov 26 16:23:50 2004 UTC (19 years, 6 months ago) by jfb
Branch: MAIN
Changes since 1.6: +15 -12 lines
Rewrite the internals of the file management code so that we do not keep
a full path to each file we load, and cache file names so we can have
multiple references to a single name. This saves a lot of memory on large
trees such as /usr/src, especially on 'Makefile', 'README' and such.
