+.TH SDEP 1 sdep\-VERSION
+
+.SH NAME
+sdep \- a simple "date+event" line parser
+
+.SH SYNOPSIS
+.B sdep
+.RB [ \-dv ]
+.IR "[+format]"
+.RB [ \-f 
+.IR "[date]" ]
+.RB [ \-t 
+.IR "[date]" ]
+.RB [ \-w
+.IR format ]
+.RB [ \-s
+.IR string ]
+
+.SH DESCRIPTION
+.B sdep
+reads lines of the form
+
+.IR "date text"
+
+from stdin and writes to stdout those lines such that
+.IR date
+is between the two dates specified by the
+.IR \-f
+and
+.IR \-t
+options, both of which default to the current minute.
+The dates should correspond to a unique minute in time. The format for
+.IR date
+can be specified with the same syntax as for
+.IR date (1).
+
+.SH OPTIONS
+
+.TP
+.B \-d
+print the default date format and exit.
+
+.TP
+.BI \-f " [date]"
+initial date for the range (default: current minute). If
+.I date
+is not specified then there will be no lower bound for the dates.
+
+.TP
+.BI \-s " string"
+change the string that separates the date from the text in the output
+lines (deafult: "\t").
+
+.TP
+.BI \-t " [date]"
+final date for the range (default: current minute). If
+.I date
+is not specified then there will be no upper bound for the dates.
+
+.TP
+.B \-v
+print version information and exit.
+
+.TP
+.BI \-w " format"
+change the format in which the date is written in the output lines.
+
+.SH EXAMPLES
+If
+.I events.txt
+contains lines formatted as
+.I "date text"
+then
+
+sdep -f <events.txt
+
+will print all the lines whose date is in the past, while
+
+sdep -t -w "%A" <events.txt
+
+will print all lines whose date is in the future, showing only the day of the
+week and the text.
+
+sdep -f "1999-01-01 00:00" -t "1999-12-31 23:59" -w "" <events.txt
+
+will show only the
+.I text
+of all lines with a date in 1999. You can specify a different format for the
+dates, for example
+
+sdep +"%m/%d/%Y %I:%M%p" -t "12/31/2020 11:59pm" -w "" <events.txt
+
+will match all dates from December 31st, 2020, one minute before midnight
+(included). Note: this only works if your locale has an am/pm format, see
+.IR date (1).
