To check out the trunk from the subversion repository,
use "svn co", e.g.

    svn co https://bacnet.svn.sourceforge.net/svnroot/bacnet/trunk/bacnet-stack/

    or for the stable releases:
    
    svn co https://bacnet.svn.sourceforge.net/svnroot/bacnet/tags/bacnet-stack-0-4-0/

Committers need to properly configure their svn client so that
the appropriate subversion properties are set on newly added files. 
One of the most important properties is the eol-style property 
that configures OS-specific line-endings for text files.

Add the configuration text below to your subversion client 
configuration file that is normally in the following location:

Windows: %USERPROFILE%\Application Data\Subversion\config
Linux:   ~/.subversion/config

Warning: Make sure the settings are merged into the appropriate 
section if it already exists, as duplicate section names can 
cause problems.

[auto-props]
### The format of the entries is:
###   file-name-pattern = propname[=value][;propname[=value]...]
### The file-name-pattern can contain wildcards (such as '*' and
### '?').  All entries which match will be applied to the file.
### Note that auto-props functionality must be enabled, which
### is typically done by setting the 'enable-auto-props' option.

To test the properties of a file:
$ svn proplist 

If a file slips into subversion without the eol-style property set, 
you can periodically run:
$ svn propset svn:eol-style native *
$ svn commit -m "changed eol-style"
