To indicate a remote source file location for a commit script, follow these steps:
[edit system scripts commit]
set file filename source url;
If the commit script is written in XSLT, using the .xsl file extension is optional, but highly recommended. If the commit script is written in SLAX, the file must include the .slax file extension.
[edit system scripts commit]
file iso.xsl {
http://my.example.com/pub/scripts/iso.xsl;
}
