The power report provides one view of national strengths.

-If the optional \*Qnum\*U argument is given, only the
-top num entries in the power chart will be displayed. Note that for
-deities, if you give a negative number, only the top num entries in
-the power chart will be displayed, and the power number rating will
-not be displayed.
+Normally, the last saved power report is shown.
+The optional arguments \*Qnew\*U and \*Qupdate\*U request a new power
+report based on up-to-date information.
+This costs 10 BTUs.
+The new report is saved for use by future power commands, except when
+a deity uses \*Qupdate\*U. This lets deities examine up-to-date power
+reports without affecting what players get to see.
.s1
-If the optional \*Qnew\*U argument is given,
-the program will take several minutes to gather information
-and generate a power report based on that up-to-date information.
-This costs several BTU's (typically 10).
+If option AUTO_POWER is enabled, the command doesn't let you save new
+power reports. Instead, the power report is updated automatically
+right before the update.
.s1
-If the optional \*Qnew\*U argument is not given,
-the program will shown you the report generated
-the last time someone asked for new data.
+If the optional \*QNUM\*U argument is given, only the
+top NUM entries in the power chart will be displayed. Note that for
+deities, if you give a negative number, only the top NUM entries in
+the power chart will be displayed, and the power number rating will
+not be displayed.

If the optional \*Qcountry\*U argument is given, then the information
-is only given for those particular countries. Countries are
-separated by the "/" character as in:
-.EX power c Fodder/19/Mirky
-Note that countries may be specified as either names or numbers.

In the power report the countries are listed
-in order of decreasing \*Qpower factor\*U,
-each being represented by a line in the following format:

The \*Qpower factor\*U is determined by the following equation:
.s1
.NF
-power factor = for each land unit calculate and add the following
- ((((land unit lcm cost / 10) * (land unit effic / 100)) +
- ((land unit hcm cost / 10) * (land unit effic / 100))) * 2)
-power factor += for each ship calculate and add the following:
- ((((ship lcm cost / 10) * (ship effic / 100)) +
- ((ship hcm cost / 10) * (ship effic / 100))) * 2)
-power factor += for each plane calculate and add the following:
- (20 * (plane effic / 100) * (nation tech level / 500))
-power factor += ((nation money / 100) + (petrol / 500) +
- ((civilians + military) / 10) + (shells / 12.5) +
- (iron / 100) + (dust / 5) + (oil / 10) + bars +
- (guns / 2.5) + (lcms / 10) + (hcms / 5))
-power factor += ((number of sectors * (average sector effic / 100)) * 10)
-power factor = ((power factor) * (nation tech level / 500))
-power factor = ((power factor) * (research factor))
