the new line number is\ 1 again 144(except if the `-rC1' option is given on the command line) -- this feature 145is intended only for formatting multiple man pages; a single man page should 146contain exactly one 147.B TH 148macro at the beginning of the file. 149.TP 150.BI ".SH [" "text for a heading" ] 151Sets up an unnumbered section heading sticking out to the left. 152Prints out all the text following 153.B SH 154up to the end of the line (resp. the text in the next line if there is no 155argument to 156.BR SH ) 157in bold face, one size larger than the base document size. 158Additionally, the left margin for the following text is reset to its default 159value. 160.TP 161.BI ".SS [" "text for a heading" ] 162Sets up an secondary, unnumbered section heading. 163Prints out all the text following 164.B SS 165up to the end of the line (resp. the text in the next line if there is no 166argument to 167.BR SS ) 168in bold face, at the same size as the base document size. 169Additionally, the left margin for the following text is reset to its default 170value. 171.TP 172.BI ".TP [" nnn ] 173Sets up an indented paragraph with label. 174The indentation is set to 175.I nnn 176if that argument is supplied (the default unit is `n' if omitted), otherwise 177it is set to the default indentation value. 178The first line of text following this macro is interpreted as a string to be 179printed flush-left, as it is appropriate for a label. 180It is not interpreted as part of a paragraph, so there is no attempt to fill 181the first line with text from the following input lines. 182Nevertheless, if the label is not as wide as the indentation, then the 183paragraph starts at the same line (but indented), continuing on the 184following lines. 185If the label is wider than the indentation, then the descriptive part of the 186paragraph begins on the line following the label, entirely indented. 187Note that neither font shape nor font size of the label is set to a default 188value; on the other hand, the rest of the text will have default font 189settings. 190The 191.B TP 192macro is the macro used for the explanations you are just reading. 193.TP 194.B .LP 195.TQ 196.B .PP 197.TQ 198.B .P 199These macros are mutual aliases. 200Any of them causes a line break at the current position, followed by a 201vertical space downwards by the amount specified by the 202.B PD 203macro. 204The font size and shape are reset to the default value (10pt resp. Roman). 205Finally, the current left margin is restored. 206.TP 207.BI ".IP [" designator "] [" nnn ] 208Sets up an indented paragraph, using 209.I designator 210as a tag to mark its beginning. 211The indentation is set to 212.I nnn 213if that argument is supplied (default unit is `n'), otherwise the default 214indentation value is used. 215Font size and face of the paragraph (but not the designator) are reset to 216its default values. 217To start an indented paragraph with a particular indentation but without a 218designator, use `""' (two doublequotes) as the second argument. 219.IP 220For example, the following paragraphs were all set up with bullets as the 221designator, using `.IP\ \\(bu\ 4': 222.RS 223.IP \(bu 4 224.B IP 225is one of the three macros used in the 226.B man 227package to format lists. 228.IP \(bu 4 229.B HP 230is another. 231This macro produces a paragraph with a left hanging indentation. 232.IP \(bu 4 233.B TP 234is another. 235This macro produces an unindented label followed by an indented paragraph. 236.RE 237.TP 238.BI ".HP [" nnn ] 239Sets up a paragraph with hanging left indentation. 240The indentation is set to 241.I nnn 242if that argument is supplied (default unit is `n'), otherwise the default 243indentation value is used. 244Font size and face are reset to its default values. 245The following paragraph illustrates the effect of this macro with hanging 246indentation set to\ 4: 247.RS 248.HP 4 249This is a paragraph following an invocation of the 250.B HP 251macro. 252As you can see, it produces a paragraph where all lines but the first are 253indented. 254.RE 255.TP 256.BI ".RS [" nnn ] 257This macro moves the left margin to the right by the value 258.I nnn 259if specified (default unit is `n');
