.SH NAME
shortc \- generate short preprocessor definitions for long C identifiers
.SH SYNOPSIS
.B shortc
[
.I -symlen
] [
.B -p
] [
.B -s
]
.I file ...
.SH DESCRIPTION
.I Shortc
searches for instances of long identifiers
in the specified
.IR files.
In its normal mode of operation
.I shortc
generates a list of preprocessor definitions that are unique in their first
seven characters.
.PP
The 
.I shortc
output is then included into each file (or a common header file) which
is processed using a flexnames version of cpp.
.PP
If no files are given
.I shortc
reads from the standard input.
.PP
The
.IR symlen
argument may be used to change the default long identifier length
from seven characters.
.PP
The \-s
option generates a sed script instead of preprocessor definitions.
The \-p
option causes
.I shortc
to parse preprocessor lines.
These options are most useful together
when flexnames support is not available from cpp.
.SH BUGS
When using cpp, preprocessor symbols must be weeded out by hand.  Otherwise
they will cause (innocuous) redefinition messages.
.PP
The \-p
option will incorrectly parse include file names which must be removed by
hand from the output.
