Subject: XSLT to transform JDiveLog to Subsurface format
X-Git-Url: http://git.tdb.fi/?p=ext%2Fsubsurface.git;a=commitdiff_plain;h=84e6f200f64721771be18564830e277f0885e117

XSLT to transform JDiveLog to Subsurface format

XSLT file to transfer dive logs from JDiveLog format to Subsurface
format. It can be used on command line with the following syntax:
	xsltproc <divelog.jlb> > <divelog.xml>

Basic functionality such as depth readings and dive information is
currently supported. However, this is only tested in metric units.

What is currently missing is at least tank changes and tank pressure (as
no sample data was available).
