SYNOPSIS

btparser [option]... [FILE]...  

DESCRIPTION

By default, btparser prints the backtrace tree created by parsing the input file.

Print a short, textual representation of the backtrace, useful for detecting the backtrace duplicates.
-s, --distances
Print Damerau–Levenshtein distances between the backtraces specified on the command line.
-g, --dendrogram
Cluster backtraces by their distance and print an ASCII representation of the dendrogram.
-l, --clusters=LEVEL
Print clusters cut from the dendrogram at the specified level.

Additional options

-i, --stdin
Read input from the standard input rather than file.
-m, --max-frames=FRAMES
When creating optimized backtrace or preparing backtrace for comparison, limit the number of frames to FRAMES. (default 8)
