The following is a listing of current problems submitted by FreeBSD users.
These represent problem reports covering all versions fo FreeBSD 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}Work on the problem has been postponed.  This happens if a
${dd_x}timely solution is not possible or is not cost-effective at
${dd_x}the present time.  The PR continues to exist, though a solution
${dd_x}is not being actively sought.  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.
