The following is a listing of current problems submitted by $project users.
These represent problem reports covering all versions including
experimental development code and obsolete releases.
${p}
Bugs can be in one of several states:
${dl}
${dt}${st}o - open${st_e}
${dd}A problem report has been submitted, no sanity checking performed.

${dt}${st}a - analyzed${st_e}
${dd}The report has been examined by a team member and evaluated.

${dt}${st}f - feedback${st_e}
${dd}The problem has been solved, and the originator has been given a
${dd_x}patch or a fix has been committed.  The PR remains in this state
${dd_x}pending a response from the originator.

${dt}${st}s - suspended${st_e}
${dd}The problem is not being worked on.  This is a prime candidate
${dd_x}for somebody who is looking for a project to do.
${dd_x}If the problem cannot be solved at all,
${dd_x}it will be closed, rather than suspended.

${dt}${st}c - closed${st_e}
${dd}A problem report is closed when any changes have been integrated,
${dd_x}documented, and tested.
