Subject Re: cvs commit: jakarta-lucene-sandbox/contributions/snowball/src/java/org/apache/lucene/analysis/snowball package.html SnowballAnalyzer.java SnowballFilter.java
Date Sat, 21 Dec 2002 02:07:32 GMT
We had this in Lucene Sandbox?  I never saw it committed, weird.

I can't get it from the repository, any idea why?

cvs server: failed to create lock directory for
`/home/cvs/jakarta-lucene-sandbox/contributions/snowball'
