Subject: Chdir into a sensible location before starting the application
X-Git-Url: http://git.tdb.fi/?p=libs%2Fcore.git;a=commitdiff_plain;h=fa82e97ed56597f2d968abdf4ebf688de4f9b618

Chdir into a sensible location before starting the application

System location accessors will ultimately return this directory.  The
default is /, which can easily cause problems.  In particular, many of
my applications expect to have their data in get_sys_data_dir()/"data".
On Android /data exists but is not readable.
