# IMPLEMENTATION NOTES
23
# This script follows the mailcross testsuite interface
24
# requirements. Type man mailcross for details.
26
# The script accepts one of more commands on the command line,
27
# and may read STDIN and write STDOUT as follows:
30
# In this case, a single email is expected on STDIN,
31
# and a list of category filenames is expected in $2, $3, etc.
32
# The script writes the category name corresponding to the
33
# input email on STDOUT.
36
# In this case, a standard mbox stream is expected on STDIN,
37
# while a suitable category file name is expected in $2. No output
38
# is written to STDOUT.
41
# In this case, a directory is expected in $2, which is examined
42
# for old database information. If any old databases are found, they
43
# are purged or reset. No output is written to STDOUT.
45
# If $1 == "describe":
46
# In this case, STDIN and the command line are ignored. A single
47
# line is written on STDOUT, describing the filter functionality.
49
# If $1 == "bootstrap":
50
# In this case, the current script is copied to the directory $2,
51
# provided the classifier we're wrapping exists on the system.
54
# In this case, a single email is expected on STDIN,
55
# and a list of category filenames is expected in $2, $3, etc.
56
# The category name in $2 represents the "true" category, and $3 $4 etc
57
# are a complete list of possible categories.
58
# The script writes the classified category name corresponding to the
59
# input email on STDOUT, and if this differs from the true category $2,
60
# then, and only then, the email is learned.
63
# Like "toe", but the input email is always learned.
