This commit slightly improves the formatting of the manuals. My
OpenBSD machine uses mandoc(1) to format manuals. I check the manuals
with `mandoc -T lint` and fix most of the warnings. I also make
other changes where mandoc didn't warn me.
roff(7) says, "Each sentence should terminate at the end of an input
line," but we often forgot this rule. I insert some newlines after
sentences that had ended mid-line.
roff(7) also says that blank lines "are only permitted within literal
contexts." I delete blank lines. This removes some extra blank lines
from mandoc's output. If I do want a blank line in the output, I call
".sp 1" to make it in man(7). If I want a blank line in the source,
but not the output, I put a plain dot "." so roff ignores it.
Hyphens used for command-line options, like \-a, should be escaped by
a backslash. I insert a few missing backslashes.
mandoc warns if the date in .TH doesn't look like a date. Our manuals
had a missing date or the RCS keyword "$Revision$". Git doesn't
expand RCS keywords. I put in today's date, 2017-01-18.
Some manuals used tab characters in filled mode. That doesn't work.
I use .nf to turn off filled mode, or I use .IP in man(7) to make the
indentation without a tab character.
ack(1) defined a macro .SB but never used it, so I delete the
definition. I also remove a call to the missing macro .RF.
mandoc warns about empty paragraphs. I deleted them. mandoc also
warned about these macro pairs in anm(1):
.SM
.B text
The .SM did nothing because the .B text is on a different line. I
changed each pair to .SB for small bold text.
I make a few other small changes.

.SH DESCRIPTION
|
|
|
|
|
.I Led
|
|
|
|
|
is a link editor for object modules,
|
|
|
|
|
It combines several
|
|
|
|
|
object programs into one,
|
|
|
|
|
resolves external references,
|
|
|
|
|
and searches archives.
|
|
|
|
|
In the simplest case several object
|
|
|
|
|
.I files
|
|
|
|
|
are given, and
|
|
|
|
|
.I led
|
|
|
|
|
combines them, producing
|
|
|
|
|
an object module which can be either
|
|
|
|
|
fed into a machine specific conversion program
|
|
|
|
|
or become the input for a further
|
|
|
|
|
.I led
|
|
|
|
|
run.
|
|
|
|
|
(In the latter case, if there are no unresolved references,
|
|
|
|
|
the
|
|
|
|
|
.B \-r
|
|
|
|
|
option must be given
|
|
|
|
|
to preserve the relocation information.)\
|
|
|
|
|
The resulting object file of
|
|
|
|
|
.I led
|
|
|
|
|
is named
|
|
|
|
|
.BR a.out .
|
|
|
|
|
.PP
|
|
|
|
|
The argument routines are concatenated in the order specified.
|
|
|
|
|
The entry point of the output is the
|
|
|
|
|
beginning of the first routine.
|
|
|
|
|
.PP
|
|
|
|
|
If an argument is an archive, its table of contents is searched
|
|
|
|
|
for names which are undefined at the point at which the argument
|
|
|
|
|
is encountered in the argument list.
|
|
|
|
|
This procedure is repeated as long as unresolved references are
|
|
|
|
|
satisfied.
|

|

This commit slightly improves the formatting of the manuals. My
OpenBSD machine uses mandoc(1) to format manuals. I check the manuals
with `mandoc -T lint` and fix most of the warnings. I also make
other changes where mandoc didn't warn me.
roff(7) says, "Each sentence should terminate at the end of an input
line," but we often forgot this rule. I insert some newlines after
sentences that had ended mid-line.
roff(7) also says that blank lines "are only permitted within literal
contexts." I delete blank lines. This removes some extra blank lines
from mandoc's output. If I do want a blank line in the output, I call
".sp 1" to make it in man(7). If I want a blank line in the source,
but not the output, I put a plain dot "." so roff ignores it.
Hyphens used for command-line options, like \-a, should be escaped by
a backslash. I insert a few missing backslashes.
mandoc warns if the date in .TH doesn't look like a date. Our manuals
had a missing date or the RCS keyword "$Revision$". Git doesn't
expand RCS keywords. I put in today's date, 2017-01-18.
Some manuals used tab characters in filled mode. That doesn't work.
I use .nf to turn off filled mode, or I use .IP in man(7) to make the
indentation without a tab character.
ack(1) defined a macro .SB but never used it, so I delete the
definition. I also remove a call to the missing macro .RF.
mandoc warns about empty paragraphs. I deleted them. mandoc also
warned about these macro pairs in anm(1):

The .SM did nothing because the .B text is on a different line. I
changed each pair to .SB for small bold text.
