source: trunk/debathena/scripts/dasource @ 25747

Revision 25747, 5.5 KB checked in by jdreed, 9 years ago (diff)
Get rid of "dirname $0" and replace with DA_SCRIPTS_DIR, which allows overriding at run time. (Trac: #1191)

3# Usage: dasource [-r REPOS] [PACKAGENAME ...]
4
5# Creates or updates a checkout and source package for each listed
6# PACKAGENAME, or for all regular packages if no PACKAGENAME is
7# specified.
8
9# If REPOS is specified, it is used in preference to the canonical
10# Athena repository trunk.
11
12# Package subdirectories are created in the cwd.  The source checkout
13# will reside in PACKAGENAME/PACKAGENAME-VERSION and the source
14# package will be created in PACKAGENAME.
