Summary: stdout, stderr and exit codes

https://bugzilla.redhat.com/show_bug.cgi?id=688447

           Summary: stdout, stderr and exit codes
           Product: Publican
           Version: 2.5
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: unspecified
          Priority: unspecified
         Component: publican
        AssignedTo: jfearn at redhat.com
        ReportedBy: tdabasin at redhat.com

I run publican package -brew -lang en-US 2> stderr.txt (redirecting stderr to
file) here's the file contents:
|Running clean process to ensure stale content is not bundled in packages.
|Clean: Removing tmp and publish directories.
|Setting up en-US
| Processing file tmp/en-US/xml_tmp/Weeks/Week11.xml ->
tmp/en-|US/xml/Weeks/Week11.xml
| Using XML::LibXSLT on /usr/share/publican/xsl/web-spec.xsl
|Kerberos authentication failed: No credentials cache found (-1765328189)

I checked error ERRORLEVEL and it says 0:
|[tomas]$ echo $?
|0

I then update my kerberos credentials and run command again stderr output:
|Running clean process to ensure stale content is not bundled in packages.
|Clean: Removing tmp and publish directories.
|Setting up en-US
| Processing file tmp/en-US/xml_tmp/Weeks/Week11.xml ->
tmp/en-|US/xml/Weeks/Week11.xml
| Using XML::LibXSLT on /usr/share/publican/xsl/web-spec.xsl

errorlevel again is 0.

How should I check if publican build failed? It would probably make sense
sending program output to stderr ONLY when there's an error during
execution(Kerberos authentication failed: No credentials cache found
(-1765328189)), not the regular program output:
|Running clean process to ensure stale content is not bundled in packages.
|Clean: Removing tmp and publish directories.
|Setting up en-US
| Processing file tmp/en-US/xml_tmp/Weeks/Week11.xml ->
tmp/en-|US/xml/Weeks/Week11.xml
| Using XML::LibXSLT on /usr/share/publican/xsl/web-spec.xsl

Also setting errorlevel to something other than 0 when publican build fails
would be good too

Thanks,
Tomas
