cvs commit: jakarta-ant/proposal/myrmidon/src/main/org/apache/tools/ant/taskdefs/file Delete.java
donaldp 02/02/02 23:10:01
Added: proposal/myrmidon/src/java/org/apache/antlib/file
Delete.java
Removed: proposal/myrmidon/src/main/org/apache/tools/ant/taskdefs/file
Delete.java
Log:
Move the delete, touch and mkdir tasks into antlib. CLean and refactor each task to make sure is closer to code-normalized. Also make sure all the messages are capable of being i18n'ed
