root/main/trunk/greenstone2/bin/script/mirror.pl @ 24362

Revision 24362, 4.5 KB (checked in by ak19, 8 years ago)

The method of locating perl has changed once more: util now defines the fuction get_perl_exec which is used by other scripts to obtain the path to the perl executable they should use.

30# This program uses w3mirror to mirror a web site.  It looks for a
31# mirror program configuration files in etc, and if it finds them then
32# it runs the mirroring software using this configuration file, and placing
33# the mirror in the import directory.
34#
35# mirror.pl can use the w3mirror program or the wget program if they are
36# installed.
37#
38# To use w3mirror, the configuration file must be in etc/w3mir.cfg.
39# To use GNU wget, the configuration file (i.e. a wgetrc file) must
40# be in etc/wget.cfg and a file of the URLs to read in etc/wget.url
